The LP38855S-1.2 is a 1.8V fixed output fast-response high-accuracy low-dropout (LDO) Linear Regulator with Enable. The device can maintain output voltage regulation with an extremely low input to output voltage drop. Fabricated on a CMOS process, the device operates from two input voltages, VBIAS provides power for the internal bias and control circuits, as well as drive for the gate of the N-MOS power transistor, while VIN supplies power to the load. The use of an external bias rail allows the part to operate from ultra-low VIN voltages. Unlike bipolar regulators, the CMOS architecture consumes extremely low quiescent current at any output load current. The use of an N-MOS power transistor results in wide bandwidth, yet minimum external capacitance is required to maintain loop stability. The fast transient response of this device makes it suitable for use in powering DSP, microcontroller core voltages and switch mode power supply post regulators.
- Stable with 10µF ceramic capacitors
- ±1.0% Precision output voltage across all line and load conditions (TJ = 25°C)
- Overtemperature and overcurrent protection

Analog Devices / Linear Technology LTC4151IMS#PBF
The LTC®4151 is a high side power monitor that operates over a wide voltage range of 7V to 80V. In default operation mode, the onboard 12-bit ADC continuously measures high side current, input voltage and an external voltage. Data is reported through the I2C interface when polled by a host. The LTC4151 can also perform on-demand measurement in a snapshot mode.
The LTC4151 features a dedicated shutdown pin to reduce power consumption. The LTC4151-1/LTC4151-2 feature split I2C data pins to drive opto-isolators. The data out on the LTC4151-1 is inverted while that on the LTC4151-2 is not.

Texas Instruments LP3853ES-2.5/NOPB
The LP3853/LP3856 series of fast ultra low-dropout linear regulators operate from a +2.5V to +7.0V input supply. Wide range of preset output voltage options are available. These ultra low dropout linear regulators respond very quickly to step changes in load, which makes them suitable for low voltage microprocessor applications. The LP3853/LP3856 are developed on a CMOS process which allows low quiescent current operation independent of output load current. This CMOS process also allows the LP3853/LP3856 to operate under extremely low dropout conditions.

Analog Devices LTC4357MPMS8#PBF
The LTC®4357 is a positive high voltage ideal diode controller that drives an external N-channel MOSFET to replace a Schottky diode. When used in diode OR and high current diode applications, the LTC4357 reduces power consumption, heat dissipation, voltage loss and PC board area. The LTC4357 easily ORs power sources to increase total system reliability.
In diode-OR applications, the LTC4357 controls the forward voltage drop across the MOSFET to ensure smooth current transfer from one path to the other without oscillation. If the power source fails or is shorted, a fast turn-off minimizes reverse current transients.

Infineon IFX78M05ABTFATMA1
The IFX78M05 monolithic 3-terminal positive voltage regulator employs internal current-limiting, thermal shutdown and safe-area compensation, making it extremely robust. The IFX78M05 is available in a fixed 5V version and is capable of delivering an output current of 0.5 A. This regulator can provide local on-card regulation, eliminating the distribution problems associated with single point regulation. This linear voltage regulator is designed for a wide variety of applications and suitable for use in harsh environments. The short-circuit current limit, limits the output current of the device. The safe-area protection feature limits the internal power dissipation, in case the internal power dissipation becomes too high, the thermal shutdown implemented prevents the device from overheating. The 5V voltage regulator is available in the TO-252 package.
