HTC Korea TAEJIN Tech · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3L

TJ7533AGF from HTC Korea TAEJIN Tech, in a SOT-89-3L. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	GND	power_in	Ground reference pin; the ground current is typically 1 µA and at most 3 µA for 1 mA < IOUT < 50 mA.
2	VIN	power_in	Input voltage pin with an operating range of 2.7 V to 30 V and an absolute maximum input supply voltage of 33 V.
3	VOUT	power_out	Regulated output pin that supplies up to 100 mA, with 3.3 V nominal output for the TJ7533AGF per the ordering table and ±2% output voltage accuracy at 1 mA.
