Product Description

The MPQ8904 is a low-current, low-dropout, linear regulator that operates on a single 2.5V-to-6.5V input supply. An external resistor controls the output voltage. The MPQ8904 can supply up to 500mA of load current. The enable pin (EN) allows the part to enter a low-current shutdown mode (EN=0). The MPQ8904 features thermal overload and current limit protection. It is available in an 8-pin QFN (2×3mm) package.
