概述

Description

LP38692SD-ADJ is an adjustable low-dropout regulator (LDO) in a compact SD package. It provides a stable output voltage set by an external resistor divider on the ADJ pin. Core idea: Vout ≈ Vref × (1 + R2/R1) + Iadj×R2, with a typical Vref around 1.2–1.25 V. Key features usually include low dropout, low quiescent current, current limit, thermal shutdown, and an enable/shutdown input. It operates from a modest input range and can supply tens to hundreds of milliamps depending on the exact variant and package. The ADJ option is useful when a non-standard rail (e.g., 1.8 V, 2.5 V, 3.3 V) is required for microcontrollers and logic. Applications include portable/battery-powered devices and MCU peripherals. For exact input/output ranges, dropout, quiescent current, pinout, and recommended resistor values, consult the LP38692SD-ADJ datasheet.

Features

Here are the typical features of LP38692SD-ADJ (adjustable LDO regulator):
- Adjustable output set by external resistor divider (Vout ≈ Vref × (1 + R2/R1); Vref ≈ 1.25 V)
- Input voltage range and output range suitable for portable apps (2.2–5.5 V input; output adjustable in roughly 1.25–3.3/5.0 V region depending on resistors)
- Low dropout operation (low Vdrop at load)
- Moderate load current capability (tens to hundreds of mA, e.g., ~150 mA class)
- Low quiescent current
- Protections: overcurrent/short-circuit protection, thermal shutdown
- Enable/Shutdown control to power the regulator on/off
- Stability with ceramic output capacitors; requires proper ESR as per datasheet
- Compact SD-packages (SOT-23-5 or similar) depending on variant
Note: exact electrical specs (ranges, currents, dropout) vary by revision; consult the datasheet for precise numbers and recommended external components.

Package

SOT-23-5 (SC-70-5) 5-pin small-outline package.
