# HTPS79333DBVR

**HXY MOSFET** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5L

HTPS79333DBVR from HXY MOSFET, in a SOT-23-5L. 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 | VIN | power_in | Input supply pin; the datasheet gives an input range of 2.0 V to 6.0 V and an absolute maximum of -0.3 V to +7 V. |
| 2 | GND | power_in | Ground reference pin for the regulator. |
| 3 | CE | input | Chip enable control; logic high above VCEH (1.1 V) enables the output and logic low below VCEL (0.4 V) puts the regulator into sleep mode, drawing 1.0 µA max standby current. |
| 4 | NC | unconnected | No connect pin; leave unconnected. |
| 5 | VOUT | power_out | Regulated output for the 3.3 V variant, with ±2% voltage accuracy and up to 250 mA output current. |
