The HT75XX-1 series is a set of three-terminal high current low voltage regulators implemented in CMOS technology. They can deliver 100mA output current and allow an input voltage as high as 24V. They are available with several fixed output voltages ranging from 3.0V to 5.0V. CMOS technology ensures low voltage drop and low quiescent current. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain variable voltages and currents.
The HT75XX-1 series is a three‑terminal low‑dropout regulator family implemented in CMOS technology. It delivers up to 100 mA output current, accepts input voltages up to 24 V, and is offered with fixed output voltages ranging from 3.0 V to 5.0 V.
Key electrical characteristics include a ±3 % output voltage tolerance, low quiescent power consumption (250 mW for TO‑92), and load/line regulation specifications. The devices are available in TO‑92, SOT‑89, and SOT‑25 packages, with detailed mechanical dimensions and tape‑and‑reel packaging data provided.
