HT76L18BRTZ

HTCSEMI · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT23-5

HT76L18BRTZ from HTCSEMI, in a SOT23-5. 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 IN power_in Regulator input; supply voltage can range from 2.5V to 5.5V, and it should be bypassed with a 1µF capacitor to GND.
2 GND power_in Ground reference pin for the regulator.
3 EN input Shutdown input; a logic low reduces the supply current to 10nA, and it should be connected to IN for normal operation.
4 BP/FB passive On the fixed-voltage version (BP), a low-leakage 0.01µF ceramic bypass capacitor reduces output noise; on the adjustable version (FB), this pin sets the output voltage.
5 OUT power_out Regulator output pin.
