# ADP162AUJZ-4.2-R7

**Analog Devices** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TSOT-23-5

ADP162AUJZ-4.2-R7 from Analog Devices, in a TSOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VIN | power_in | Regulator Input Supply, 2.2 V to 5.5 V. Bypass VIN to GND with a 1 µF or greater ceramic capacitor. |
| 2 | GND | power_in | Ground reference for the regulator. |
| 3 | EN | input | Enable Input. Drive EN high (VIH ≥ 1.2 V) to turn on the regulator; drive EN low (VIL ≤ 0.4 V) to shut it down (shutdown current typ. 50 nA). For automatic startup, tie EN to VIN. |
| 4 | NC | unconnected | No Connect. This pin is not internally connected. Connect to GND or leave open. |
| 5 | VOUT | power_out | Regulated Output Voltage, fixed 4.2 V, up to 150 mA. Bypass VOUT to GND with a 1 µF or greater ceramic capacitor. The ADP162 does not include an internal output discharge resistor. |
