TLE4299 is a monolithic voltage regulator with fixed 5-V output, supplying loads up to 150 mA. It only needs a quiescent current of typical 65 µA.
The TLE 4299 is a monolithic PNP‑based low‑drop linear regulator that provides a fixed 5 V output with a ±2 % tolerance. It supplies up to 150 mA load current while drawing a typical quiescent current of about 65 µA. The device includes an inhibit function to shut off the regulator when not needed, a power‑on reset, an adjustable under‑voltage reset, and an early‑warning sense output.
The regulator operates from an input voltage range of 5.5 V to 45 V and is specified for an ambient temperature range of –40 °C to 150 °C. It is offered in two surface‑mount packages, P‑DSO‑8‑3 and P‑DSO‑14‑8, with pin‑compatible layouts. Absolute‑maximum ratings and thermal data are provided for safe design, and the part includes protection against overload, short‑circuit, reverse polarity, and over‑temperature conditions.
