The STMicroelectronics L387AH is a 5V linear voltage regulator featuring a very low dropout voltage and a reset output. This makes it particularly useful for battery-powered equipment where power consumption needs to be minimized, thereby prolonging battery life.
The regulator is designed to provide stabilized 5V supplies in consumer and industrial applications. A key feature is its reset output, which provides a signal for microprocessor systems. This output generates a reset signal when power is applied (after a programmable delay) and goes low when power is removed, effectively inhibiting the microprocessor. An hysteresis on the reset delay capacitor enhances immunity to ground noise.
Key electrical specifications include a precise output voltage of 5V with a ±4% tolerance and an output current capability exceeding 500mA. The device has a DC input voltage rating of up to 35V and operates within a junction and storage temperature range of -55 to 150°C. The L387AH comes in a DIP package, suitable for various mounting needs.
Its high noise immunity and reset function make the L387AH a suitable choice for applications requiring stable power and reliable system reset capabilities.
