LT1962EMS8-1.5#PBF

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The LT1962EMS8-1.5#PBF is a micropower, low noise, low dropout linear regulator from Analog Devices Inc., housed in an 8-lead MSOP package. It provides a fixed regulated output voltage of 1.5V with a maximum continuous output current capability of 300mA. The device operates within a wide input voltage range of 1.8V to 20V and maintains a typical dropout voltage of 270mV at full load. Quiescent current is specified at 30µA during operation and drops below 1µA in shutdown mode. Internal protection circuitry includes reverse battery protection, overcurrent limiting, and thermal limiting.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators FAQ

How is low output noise achieved?

Output noise can be reduced to 20µVRMS over a 10Hz to 100kHz bandwidth by adding a 0.01µF bypass capacitor between the output and the BYP pin.

What happens if the input voltage is reversed?

The device incorporates reverse battery protection, acting like a diode in series with the input to prevent reverse current flow and protect both the regulator and the load.
