Infineon TLE 4276 Low-Drop Voltage Regulator Datasheet
The TLE 4276 is a low‑drop voltage regulator offered in TO‑220, TO‑263 and SOT‑23 packages. It can deliver a fixed output of 5 V, 8.5 V, 10 V or an adjustable voltage, with a tolerance of less than ±4 %. The device supports up to 400 mA output current and includes an inhibit input that reduces quiescent current below 10 µA when switched off.
The regulator features built‑in protection against overload, over‑temperature, short‑circuit and reverse polarity. It operates from an input voltage range of 4 V to 42 V, and its dropout voltage is typically 250‑500 mV. Electrical characteristics such as PSRR (≈54 dB at 100 Hz) and temperature range (‑40 °C to 150 °C) are documented, along with pin assignments and recommended external component values for stable operation.
