The ADR4520/ADR4525/ADR4530/ADR4533/ADR4540/ ADR4550 devices are high precision, low power, low noise voltage references featuring ±0.02% maximum initial error, excellent temperature stability, and low output noise. This family of voltage references uses an innovative core topology to achieve high accuracy while offering industry-leading temperature stability and noise performance. The low, thermally induced output voltage hysteresis and low long-term output voltage drift of the devices also improve system accuracy over time and temperature variations. A maximum operating current of 950 μA and a maximum low dropout voltage of 300 mV allow the devices to function very well in portable equipment.
The ADR4520/ADR4525/ADR4530/ADR4533/ADR4540/ ADR4550 series of references are each provided in an 8-lead SOIC package and are available in a wide range of output voltages, all of which are specified over the extended industrial temperature range of −40°C to +125°C. The ADR4525W, available in an 8-lead SOIC package, is qualified for automotive applications.

Texas Instruments LP3963ES-3.3/NOPB
The LP3963ES-3.3/NOPB is a 3.3V fixed output fast ultra-low-dropout (LDO) Linear Regulator operate from a 2.5 to 7V input supply. This device respond very fast to step changes in load which makes them suitable for low voltage microprocessor applications. The device is developed on a CMOS process which allows low quiescent current operation independent of output load current. This CMOS process also allows the device to operate under extremely low-dropout (LDO) conditions. The dropout voltage is typically 80mV at 300mA load current and 800mV at 3A load current.
- Low ground pin current
- 0.06% Load regulation
- 15µA Quiescent current in shutdown mode
- ±1.5% Output voltage accuracy
- ERROR flag indicates output status
- Minimum output capacitor requirements
- 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 TPS27081ADDCR
The TPS27081ADDCR is a high-side Load Switch features industry-standard ESD protection on all pins providing better ESD compatibility with other on board components. The TPS27081A level shifts ON/OFF logic signal to VIN levels and supports as low as 1-V CPU or MCU logic to control higher voltage power supplies without requiring an external level-shifter. Switching a large value output capacitor CL through a fast ON/OFF logic signal may result in an excessive inrush current. To control the load inrush current, connect a resistor R2 and add an external capacitor C1 as shown in the Simplified Schematic in the Technical Data Sheet. To configure the TPS27081A to achieve a specific slew rate, refer to the Application and Implementation section. A single pull-up resistor R1 is required in standby power switch applications. In such applications connect the R2 pin of the TPS27081A to the system ground when inrush current control is not required.
- Adjustable turn-on and turnoff slew rate control through external R1, R2 and C1
- Supports a wide range of 1.2 to 8V supply inputs
- Integrated NMOS for PFET control
- Full ESD protection (all pins)
- Low ON-resistance, high-current PFET
- Ultralow leakage current in standby (typical 100nA)
