概述

Description

LP3470IM5X-4.38 is a fixed-output DC-DC buck regulator (power-management IC) designed for portable electronics. The “-4.38” suffix indicates a 4.38 V output rail. It is packaged in an IM5X 5×5 mm form factor and integrates the high-side/low-side switches with a control loop (often current-mode). Key benefits typically include high efficiency, compact size, enable control, and protection features (overcurrent and thermal shutdown). The fixed-output variant usually requires only a few external passives: input capacitor, inductor, and output capacitor (feedback resistors are not needed). Typical applications are power rails for microprocessors, memory, or peripherals in battery-powered devices and compact consumer electronics. For exact electrical specs (input voltage range, maximum output current, switching frequency, pinout, and layout recommendations), consult the manufacturer’s datasheet for the LP3470IM5X-4.38 variant.

Features

I don’t have the exact datasheet in front of me. LP3470IM5X-4.38 appears to be a fixed-output voltage regulator in the IM5X (5×5 mm) package with a 4.38 V output. Typical features you’d expect (verify against the datasheet):
- Fixed output: 4.38 V
- IM5X 5×5 mm package (QFN/DFN style)
- Low dropout LDO
- Low quiescent current
- Enable/disable pin
- Short-circuit/overcurrent protection
- Thermal shutdown protection
- Input/output protection features (ESD, reverse protection)
For precise specs (input range, exact protections, temp range, and package details), please share or check the official datasheet.

Package

It uses a 5x5 mm QFN (leadless) package.

Pinout

- Pin count: 5 pins
- Function: Fixed-output low-dropout regulator (LDO) with a 4.38 V output. Provides input, ground, output, enable, and a bypass/no-connect pin (exact pin order depends on orientation package; refer to the datasheet for the exact pinout).

Application

LP3470IM5X-4.38 is a fixed 4.38 V LDO regulator. Typical applications include:
- LCD/TFT display bias sources (Vcom) and other bias rails
- Camera sensors and analog front-end bias supplies
- Auxiliary/standby rails for microcontrollers and DSPs in portable devices
- Automotive/industrial auxiliary regulators needing a stable 4.38 V
- General embedded systems needing a dedicated fixed 4.38 V rail

Equivalent

LP3470IM5X-4.38 is a fixed 4.38 V LDO regulator in an M5X package. Exact equivalents depend on function, package, and specs (input range, temp range). To give precise substitutes, please share:
- device type (LDO vs. reset supervisor),
- package size/pinout (M5X variant),
- max input voltage and temp range.
With those, I can list direct cross-references from TI, Analog Devices, ST, Microchip, etc.
