Siemens TLE 4261-2 5‑V Low‑Drop Voltage Regulator Datasheet
The TLE 4261-2 regulates an input voltage up to 42 V (65 V for <400 ms) to a precise 5 V output with 2 % accuracy. It features low quiescent current, reverse‑polarity protection, over‑temperature shutdown, and an integrated watchdog that monitors a connected microprocessor.
Key electrical specifications include a maximum output current of >500 mA, drop voltage of 0.35‑0.5 V, load regulation of 15‑35 mV, ripple rejection of 54 dB at 100 Hz, and an operating temperature range of –40 °C to 150 °C. The device is offered in P‑TO220‑7 and P‑DSO‑20‑6 packages with detailed pin definitions for input, inhibit, reset, watchdog and output functions.
