The L387A is a very low dropout voltage regulator in a Pentawatt[package specifically designed to provide a regulated 5V power supply for consumer and industrial applications. With its extremely low input/thank output voltage drop this device is very useful in battery powered equipment, reducing consumption and extending battery life. The reset output makes the L387A particularly suitable for microprocessor systems. This output provides a reset signal on power-up (with an externally programmable delay) and power-off when it goes low, inhibiting the microprocessor. A power-on-reset delay capacitor hysteresis induces immunity to ground noise.
