TP142C33C5

TECH PUBLIC · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-353

TP142C33C5 from TECH PUBLIC, in a SOT-353. 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 pin. Operating range 1.2V to 5.5V; absolute maximum -0.3V to 6.5V referenced to GND. Bypass to GND with a 1uF ceramic capacitor as close to the pin as possible.
2 GND power_in Device ground reference. Carries the quiescent current (typ. 2uA) and the internal analog return. Connect to the system ground plane with a low-impedance path.
3 EN input Enable control input. Drive high (VIH ≥ 1.0V) to turn the regulator on, low (VIL ≤ 0.4V) to place it in shutdown (ISD typ. 0.1uA). EN input current is typically 10nA at VEN=5V. Absolute maximum -0.3V to 6V. Do not leave floating.
4 NC unconnected No internal connection. May be left floating or tied to GND for mechanical/EMI reasons.
5 VOUT power_out Regulated output pin. Fixed 3.3V output (TP142C33 variant) with ±2% accuracy, delivering up to 450mA (typical current limit 500mA). Requires a 1uF ceramic or tantalum output capacitor for stability. When EN=low, output is discharged through an internal ~100Ω resistor.
