概述

Description

LP38500SD-ADJ/NOPB is an adjustable low-dropout regulator (LDO) from TI’s LP38500 family. The ADJ variant lets you set the output with an external resistor divider (Vout ≈ Vref × (1 + R2/R1) + Iadj × R2; Vref is typically around 1.25 V, Iadj is small). The NOPB suffix denotes a lead-free version; SD indicates the specific package type. It provides typical LDO features such as low dropout at practical loads, low quiescent current, and protection (current limit/thermal shutdown). It’s suitable for battery-powered devices, microcontroller supplies, and other point‑of‑load applications. For exact electrical specs (VIN range, adjustable Vout range, Iout, dropout, Iq) and recommended output capacitor ESR/values, consult the LP38500SD-ADJ/NOPB datasheet. If you’d like, I can give a quick setup guide for choosing resistors to obtain a desired Vout and a pinout sketch based on the package.

Features

LP38500SD-ADJ/NOPB is an adjustable low-dropout regulator (LDO). Key features:
- Adjustable output via external resistor divider (ADJ)
- Up to 1 A output current
- Low dropout for near-rail operation
- Enable/shutdown input
- Built-in protection: current limit and thermal shutdown
- Good line and load regulation with fast transient response
- Pb-free and RoHS compliant (NOPB)
- Compact SD package option (suitable for space-limited designs)
Applications include battery-powered and portable electronics where an adjustable, efficient LDO is needed.

Package

SOT-23-5 (SC-70-5) package, Pb-free (NOPB).

Pinout

- Pin count: 5 pins (SOT-23-5 package)
- Function: Adjustable low-dropout (LDO) voltage regulator. It provides a stable output voltage set by an external resistor divider using pins for Vin, Vout, GND, ADJ, and a BYP (bypass) or similar reference pin for noise reduction. External resistors determine Vout (Vout ≈ Vref × (1 + R2/R1) with Iadj typically small).

Manufacturer

Manufacturer: Texas Instruments (TI).
What kind of company: TI is a global semiconductor company that designs and manufactures analog, mixed-signal, and embedded processing integrated circuits for a wide range of electronics applications.

Application

LP38500SD-ADJ/NOPB is an adjustable low-dropout regulator used to generate clean, stable voltages in compact PMIC power-management solutions. Typical applications:
- Battery-powered and portable devices (phones, cameras, wearables)
- Microprocessor/microcontroller supply rails
- Post-regulation for switching regulators
- Analog/digital mixed-signal circuits needing low-noise Vout
- Automotive and industrial equipment requiring a robust, adjustable LDO

Equivalent

Equivalent parts to LP38500SD-ADJ/NOPB (TI adjustable LDO in SOT-23) depend on target Vout and Iout. Common cross-references:
- TI LP2985-ADJ (150 mA, SOT-23-5)
- TI TLV1117-ADJ (1 A, SOT-223/SOT-23)
- AMS1117-ADJ (1 A, SOT-223)
- LM317L-ADJ (adjustable, ~1.5 A, TO-92/TO-220)
