MIC5205YM5TR – MICREL

The MIC5205YM5TR is a low-dropout (LDO) linear regulator manufactured by MICREL (now Microchip Technology). This device provides a regulated positive output voltage adjustable from near zero up to the input voltage, with a maximum output current of 150mA. It is housed in a space-saving SOT23-5 surface-mount package, making it suitable for portable and space-constrained applications. The regulator employs an internal NMOS pass transistor, which contributes to its low dropout voltage, typically less than 170mV at full load. Stability is achieved with small ceramic output capacitors, reducing the overall bill of materials. The MIC5205YM5TR incorporates overcurrent and overtemperature protection, enhancing its robustness in demanding operating conditions. Its adjustable output voltage is configured via external resistors connected to the feedback pin.
