Descripción general

Description

LT1963EST-1.8#TRPBF is a fixed-output voltage regulator from Linear Technology (now Analog Devices). The -1.8 denotes a 1.8 V output. The “EST” suffix indicates an extended-temperature variant, and “TRPBF” means Pb-free, Tape & Reel packaging.
Key points:
- Fixed 1.8 V output in a compact package for powering digital cores, memories, or logic rails.
- Part of the LT1963 family, designed for simple deployment with minimal external components (no resistor network required for fixed output).
- Includes typical regulator protections (e.g., overcurrent/short-circuit protection and thermal shutdown).
Important: exact electrical specs (input voltage range, dropout, quiescent current, output accuracy, PSRR, line/load regulation, thermal performance, and pinout) vary by package and revision. For precise figures, consult the LT1963EST-1.8 datasheet and the product page.
If you want, I can link to or pull the latest datasheet and a quick-start guide.

Features

Here are the key features of LT1963EST-1.8#TRPBF:
- Fixed output: 1.8 V LDO regulator
- Extended temperature range: -40°C to +125°C
- Low dropout and low quiescent current
- Good line and load regulation with solid PSRR
- Fast transient response for supply stability
- Protection: overcurrent/short‑circuit protection and thermal shutdown
- Packaging: Pb-free with TRPBF (Tape & Reel) option
- Suitable for powering digital logic, microcontrollers, and other 1.8 V rails
Note: For exact electrical specs (input range, dropout voltage, quiescent current, etc.), please consult the current datasheet.

Package

It’s in an 8‑lead MSOP package (MSOP‑8), Pb‑free, in Tape & Reel packaging (TRPBF).

Pinout

Five pins (SOT-23-5 package). It is a fixed-output low-dropout regulator (LDO) with a 1.8 V output and an enable/shutdown control pin, plus input and ground pins.

Manufacturer

Manufacturer: Analog Devices, Inc. (the former Linear Technology).
Company type: A multinational semiconductor company that designs and manufactures analog, mixed-signal, and DSP integrated circuits.

Application

LT1963EST-1.8#TRPBF is an 1.8 V low-dropout regulator (extended-temp). Typical applications: local 1.8 V core/I/O supplies for FPGAs, microprocessors, and DSPs; bias/reference rails for ADC/DACs and RF/analog circuits; noise-sensitive instrumentation and audio; battery-powered/portable devices needing a stable 1.8 V rail; point-of-load regulation in power supplies (industrial/automotive environments).

Equivalent

LT1963EST-1.8#TRPBF is a 1.8V fixed-output LDO. Common cross-ref (1.8V LDOs in similar Pb-free packages):
- Analog Devices: ADP170AUJZ-1.8; ADP3330-1.8
- Texas Instruments: TLV70018DBVR; TPS7A01-1.8
- On Semiconductor: NCP4680-1.8
Note: verify pinout, current rating and package; use distributor cross-reference for exact substitution.
