概述

Description

TPS70618DBVR is a fixed-output low-dropout regulator from TI (TPS706x family). It provides a regulated 1.8 V rail to power microcontrollers, sensors, and other digital logic from a higher input supply (up to about 5.5 V). Key advantages include very low quiescent current, low dropout, and built-in protection features (short-circuit and thermal shutdown) plus an enable (EN) pin for easy_shutdown control. The DBVR suffix indicates a tape‑and‑reel package of the SOT‑23‑5 style (DBV) footprint, suitable for compact, battery-powered designs. Ideal for portable or low-power devices needing a small, efficient 1.8 V regulator.

Features

TPS70618DBVR features (typical):
- Fixed 1.8-V output low-dropout regulator
- Ultra-low quiescent current (very low standby power)
- Low dropout voltage for battery-powered apps
- Enable (EN) pin to disable/enable device
- Overcurrent/short-circuit protection and thermal shutdown
- Stable with ceramic output capacitors (low ESR)
- Wide input range above 1.8 V
- Small 5-pin DBV package (RoHS-compliant), suitable for compact designs
- Suitable for portable/space-constrained electronics with simple external caps
Note: For exact electrical specs (input range, dropout, accuracy, cap requirements) refer to the TI TPS70618 datasheet.

Package

SOT-23-5 (SC-70-5) package; Tape-and-Reel (DBVR suffix).

Pinout

- Pin count: 5 pins (SOT-23-5, DBV package)
- Functions: VIN (input supply), GND (ground), VOUT (regulated output, 1.8 V), EN (enable control), BYP (bypass for an external capacitor to reduce noise).

Manufacturer

Manufacturer: Texas Instruments (TI).
What kind of company: TI is an American multinational semiconductor company headquartered in Dallas, Texas, that designs and manufactures analog and embedded processing integrated circuits.

Application

TPS70618DBVR is a 1.8‑V fixed‑output LDO. Applications: battery-powered and portable devices needing a stable 1.8‑V supply; powering microcontrollers, CPU cores, memory, FPGAs/ASICs, and analog front-ends; sensor modules; wearables and IoT devices; consumer electronics (cameras, displays, audio); telecom/networking equipment needing low quiescent current; any compact system needing a small, low‑noise 1.8‑V regulator.
