TPNCP500SN33T1G

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

TPNCP500SN33T1G 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 Unregulated supply input. Operating range 1.2V to 5.5V; absolute maximum -0.3V to 6.5V referenced to GND. Bypass to GND with a 1uF-10uF ceramic capacitor placed close to the pin.
2 GND power_in Device ground reference and return for the internal regulator control loop. Tie to the system ground plane.
3 EN input Active-high enable input. VIH >= 2V turns the regulator on; VIL <= 0.6V forces shutdown (ISD typ 0.01uA, max 0.5uA). EN input current ~10nA typ at VEN=5V. Do not leave floating; absolute maximum -0.3V to 6V.
4 NC unconnected No internal connection. Leave floating or tie to GND for mechanical stability; do not connect to any active net.
5 VOUT power_out Regulated fixed 3.3V output, up to 600mA continuous. Requires a 1uF-10uF ceramic or tantalum output capacitor to GND for stability. Absolute maximum -0.3V to 6V; internal current limit typ 1100mA, thermal shutdown at 155C.
