Texas Instruments Voltage Regulators - Linear LP3874EMP-ADJ

The LP3874EMP-ADJ is a linear voltage regulator from Quarktwin Technology Ltd. designed to provide a stable output current of 0.8A with ultra-low dropout voltage, typically 240mV at maximum load. It operates with input supply voltages ranging from +2.5V to +7.0V and offers multiple preset output voltage options from 1.8V to 5.0V, with an output voltage accuracy of ±1.5% at room temperature. The device features a low ground pin current of approximately 6mA at full load and a shutdown mode that reduces quiescent current to 10nA. Additionally, it includes an error flag to indicate output status and a sense pin for improved load regulation at remote loads. The LP3874EMP-ADJ is suitable for applications such as microprocessor power supplies, battery chargers, and other battery-powered devices, and is available in SOT-223-5 packaging.
