Description

The AZ431-B is a three-terminal adjustable shunt regulator with guaranteed thermal stability over a full operation range. It features sharp turn-on characteristics, low temperature coefficient and low output impedance, which make it ideal substitute for Zener diode in applications such as switching power supply, charger and other adjustable regulators.

Features

1. Programmable Precise Output Voltage from 2.5V to 18V

2. High Stability under Capacitive Load

3. Low Temperature Deviation: 4.5mV Typical

4. Low Equivalent Full-range Temperature Coefficient with 20PPM/oC Typical

5. Sink Current Capacity from 1mA to 100mA

6. Low Output Noise

7. Wide Operating Range of -40 to 125oC

Applications:

1. Charger

2. Voltage Adapter

3. Switching Power Supply

4. Graphic Card

5. Precision Voltage Reference

Part Number: LP2985AIM5-4.5

Marking : LA7A

Function: Micropower 150 mA Low-Noise Ultra Low-Dropout Regulator

Package: SOT-23, DSBGA 5 Pin type

Manufacturer: Texas Instruments

Pinouts:

 

Description

The LP2985AIM5-4.5 low noise linear regulator delivers up to 150-mA output current and only requires 300-mV dropout voltage of input to output. Using an optimized VIP (Vertically Integrated PNP) process, the LP2985-N delivers unequalled performance for all battery powered designs.

The LP2985-N device provides 1% tolerance precision output voltage with only 75 µA quiescent current at 1 mA load and 850 µA at 150 mA load. By adding a 10-nF bypass capacitor, the output noise can be reduced to 30 µV RMS in a 30-kHz bandwidth.

Features

1. Input Voltage Range: 2.5 V to 16 V

2. Ultra Low-Dropout Voltage

3. Ensured 150 mA Output Current

4. Requires Minimum External Components

5. Stable With Low-ESR Output Capacitor
