HTC Korea TAEJIN Tech · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5L

TJ5205SF5-ADJ from HTC Korea TAEJIN Tech, in a SOT-23-5L. 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 Supply input. Operating range 2.5V to 16V (absolute max 20V). Bypass locally to GND.
2 GND power_in Device ground reference and quiescent-current return.
3 EN input Enable/Shutdown input, CMOS/TTL compatible. Logic high (>=2.0V) enables the regulator; logic low (<=0.4V) or open shuts it down (quiescent drops to ~0.01uA). Absolute max 20V.
4 BYP/ADJ input Adjustable feedback / reference-bypass pin. On the ADJ version this is the feedback input from an external R1/R2 divider from VOUT to GND (VREF = 1.242V, VOUT = 1.242 x (1 + R2/R1), VOUT_min = 2.0V). An optional ~470pF bypass cap from this node to GND lowers output noise; may be left open if low-noise operation is not required.
5 VOUT power_out Regulated output. Guaranteed 150mA drive, typical dropout 165mV at 150mA. Requires a 2.2uF (typ.) output capacitor to GND for stability.
