The TPS73701DCQ is a linear low-dropout (LDO) Voltage Regulator uses an NMOS pass element in a voltage-follower configuration. This topology is relatively insensitive to output capacitor value and ESR, allowing a wide variety of load configurations. Load transient response is excellent, even with a small 1µF ceramic output capacitor. The NMOS topology also allows very low dropout. This device uses an advanced BiCMOS process to yield high precision while delivering very low dropout voltages and low ground pin current. Current consumption, when not enabled, is less than 20nA and ideal for portable applications. This device is protected by thermal shutdown and fold-back current limit. It features reverse current blockage and freedom from output capacitor constraints. These features combined with an enable input makes the device ideal for portable applications.

The LM338T/NOPB is an adjustable 3-terminal positive Voltage Regulator, capable of supplying in excess of 5A over a 1.2 to 32V output range. They are exceptionally easy to use and require only 2 resistors to set the output voltage. Careful circuit design has resulted in outstanding load and line regulation-comparable to many commercial power supplies. A unique feature of the LM338T/NOPB family is time-dependent current limiting. The current limit circuitry allows peak currents of up to 12A to be drawn from the regulator for short periods of time. This allows the LM338T/NOPB to be used with heavy transient loads and speeds start-up under full-load conditions. Under sustained loading conditions, the current limit decreases to a safe value protecting the regulator.

• Current Limit Constant with Temperature
• P+ Product Enhancement Tested
• Output is Short-circuit Protected
• Green Product, No Sb/Br

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
