概要

Description

The LP2985IM5X-3.6 is a fixed‑output low‑dropout regulator from TI’s LP2985 family. It provides a regulated 3.6 V from a 1.8–6 V input and is offered in the IM5X (SOT‑23‑5) package with an enable/shutdown pin. It can source up to about 250 mA with very low quiescent current (tens of µA) and exhibits a low dropout voltage suitable for battery-powered apps. To ensure stability, use a small input capacitor near VIN and a suitable output capacitor (typically 2.2–10 µF, ceramic such as X5R/X7R). The device also includes protection features (short‑circuit and thermal shutdown) and provides good line/load regulation. Applications include microcontrollers, sensors, and other portable electronics that need a fixed 3.6 V supply. Always consult the datasheet for exact pinout, capacitor recommendations, ESR limits, and thermal considerations.

Features

Key features of LP2985IM5X-3.6 (3.6 V fixed LDO in IM5X package):
- Fixed output: 3.6 V
- Output up to 150 mA
- Low dropout regulator for battery apps
- Low quiescent current
- Good line and load regulation; typical output accuracy ~±2%
- Low output noise
- Stable with ceramic output capacitors
- Protection: thermal shutdown and current-limit
- RoHS-compliant, in 5-pin SOT-23 (IM5X) package
- Operating temperature range: −40°C to +125°C
Note: Refer to the datasheet for exact numbers (quirky tolerances, capacitor needs, and input range).

Package

The LP2985IM5X-3.6 is in a 5-pin SOT-23 package (TI package code M5); the trailing "X" indicates tape-and-reel shipment.

Pinout

- Pin count: 5 pins (SOT-23-5/SC-70-5 style).
- Function: Fixed-output low-dropout regulator. Outputs 3.6 V. Pins: VIN (input), VOUT (regulated 3.6 V), GND (ground), EN (enable control), BYP (bypass for noise reduction/PSRR improvement).

Manufacturer

Manufacturer: Texas Instruments (TI).
What kind of company: Texas Instruments is an American multinational semiconductor company that designs and manufactures analog and embedded processing integrated circuits—including power-management chips like the LP2985 LDO regulator—microcontrollers, sensors, and related semiconductor solutions for industrial, automotive, consumer and communications markets. It is headquartered in Dallas, Texas.

Application

Applications of LP2985IM5X-3.6:
- Portable/battery-powered electronics needing a fixed 3.6 V regulator
- Powering microcontrollers, memories, ASICs/FPGA, RF modules
- Sensors, ADC/DAC front-ends, analog/digital ICs
- Wearables, handheld instruments, medical devices, cameras
- Space-constrained designs using small packages (SOT-23-5/MSOP) with low quiescent current

Equivalent

LP2985IM5X-3.6 is TI’s 150 mA fixed 3.6 V LDO in a SOT-23-5 package. There isn’t a widely used exact pin-for-pin equivalent. For substitutes, look for other fixed 3.6 V LDOs with the same footprint and current, e.g., MIC5205-3.6 or similar, then verify pinout, dropout, quiescent current, and package via cross-reference tools from TI, Microchip/Micrel, Onsemi, Torex, etc.
