L4987 series is a very low dropout regulator available in PPAK. The very low dropout-voltage (0.5V Max at 200 mA) and the very low quiescent current make it particularly suitable for low noise, low power applications, and in battery powered systems.
The L4987 series are very low-drop voltage regulators designed for low-noise, low-power applications and battery-powered systems. They feature a dropout voltage as low as 0.25V and quiescent current as low as 90 µA in off mode. The regulators include a logic-controlled shutdown function and an output flag to indicate dropout conditions. Available in PPAK package with output voltages of 3.3V, 5V, 8.7V, and 12V. Suitable for automotive and portable electronics due to input voltage protection up to 40V.
