HT7528-1

MSKSEMI · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3

HT7528-1 from MSKSEMI, in a SOT-89-3. 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 pin, the common reference for the regulator (datasheet gives no electrical limit for this pin).
2 VIN power_in Input pin; the datasheet rates the input voltage at 24 V maximum and recommends placing the input capacitor close to the VIN pin.
3 VOUT power_out Regulated output pin; for HT7528-1 the output is 2.8 V typical (2.744 V to 2.856 V) with 100 mA typical output current, and the datasheet requires an output capacitor larger than 2.2 μF to ground, tantalum recommended.
