Descripción general

Description

LT1963ES8-3.3#PBF is a fixed 3.3-volt low‑dropout regulator in an 8‑pin package (ES8 usually MSOP-8/SO-8 style; PBF means Pb‑free). It’s part of the LT1963 family from Linear Technology (now Analog Devices) and is used to generate a stable 3.3V rail from a higher input. Key features typically include: a fixed 3.3V output, enable/shutdown control, current‑limit protection, thermal shutdown, and good line/load regulation. It requires an appropriate output capacitor (with ESR within the datasheet’s range) and a suitable input supply to meet the load current with dropout considerations. The enable pin lets you turn the regulator on/off. For exact electrical specs, pinout, input/output ranges, quiescent current, and layout recommendations, consult the LT1963 datasheet and the Analog Devices product page.

Features

Here are concise features of LT1963ES8-3.3#PBF:
- Fixed 3.3 V output LDO regulator in an 8‑pin ES8 Pb‑Free (PBF) package.
- Enable/shutdown input to turn the regulator on/off.
- Wide input voltage range above 3.3 V (suitable for various sources).
- Low dropout with low quiescent current for efficiency.
- Internal protection: current limit and thermal/shutdown protection.
- Short‑circuit and protection against fault conditions.
- Output capacitor requirements (stability depends on capacitor ESR; follow datasheet).
- Good line/transeunt regulation and low output ripple/noise.
- RoHS compliant; operating temp typically from -40°C to 125°C.
Note: Exact electrical numbers (dropout, quiescent current, max load) vary by variant and conditions. Refer to the datasheet (LT1963ES8-3.3#PBF) for precise specs.
