TP172CADJS5

TECH PUBLIC · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

TP172CADJS5 from TECH PUBLIC, in a SOT-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 Input supply voltage. Operating range 1.2 V to 5.5 V (absolute max 6.5 V vs GND). A 1 uF input capacitor to GND is recommended for stability.
2 GND power_in Device ground reference. Return path for supply and internal control circuitry.
3 EN input Enable control input. VIH >= 2 V (max) enables the regulator; VIL <= 0.6 V (min falling) forces shutdown. EN input current ~10 nA typ at 5 V. Absolute max -0.3 V to 6 V vs GND. Do not float.
4 SNS input Feedback (sense) input for the internal error amplifier; internal reference VFB = 0.8 V. Connect to an external resistor divider from VOUT to set the output: R1 = R2 * (VOUT/0.8V - 1), with R2 < 24 kOhm. SNS input current ~0.7 uA typ.
5 VOUT power_out Regulator output. Delivers up to 600 mA with typical dropout of 0.32 V at 600 mA / VOUT=3.3 V. Stable with a >=1 uF ceramic or tantalum output capacitor. When EN=0, an internal ~100 Ohm discharge resistance pulls VOUT down.
