LT1761ES5-3#TRPBF

LT1761ES5-3#TRPBF is a fixed-output, high-current low-dropout regulator from Linear Technology (now Analog Devices). The ES5-3 designation indicates a fixed 3.3V output in a small 5‑pin package (typ. TSOT-23/5 style); TRPBF means Pb‑free, Tape & Reel packaging.
Key points:
- Fixed output: 3.3 V
- Output capability: up to about 3 A
- Input range: roughly 3–20 V
- Dropout: a few hundred millivolts at full load
- Protections: current limit and thermal shutdown; enable/shutdown control
Usage notes:
- Use recommended input and output capacitors (low ESR; tens of µF on the output, appropriate input cap as per datasheet)
- Ground, Vin, Vout, and EN pins per the footprint
- Use EN to enable/disable the regulator and manage thermal conditions
Applications:
- Point-of-load regulation in telecom, automotive, industrial, and battery-powered systems
For exact electrical specs, pinout, footprint, and capacitor recommendations, see the LT1761 datasheet for the ES5-3 variant.

Here are the key features of LT1761ES5-3#TRPBF (3.3V fixed output version):
- 3 A low-dropout linear regulator
- Fixed output: 3.3 V
- Internal current limit and thermal shutdown for short-circuit protection
- Stable with a wide range of output capacitors, including ceramic types
- Suitable for battery-powered applications (low quiescent current)
- Small ES5 package (SOT-23-5), Pb-free, Tape & Reel packaging
Note: For exact electrical specs (input range, dropout, line/load regulation), consult the current datasheet.

- Pin count: 5 pins (SOT-23-5/ES5 package)
- Function: Fixed 3.3V low-dropout regulator (LDO) with enable (EN) and bypass (BYP) pins for noise reduction; provides IN, GND, OUT, EN, BYP.

- Manufacturer: Analog Devices, Inc. (ADI). The LT1761 was originally from Linear Technology, which ADI acquired in 2017; the part is now sold under the Analog Devices name.
- What kind of company: A multinational American semiconductor company that designs, develops, and manufactures analog, mixed-signal, and digital signal processing integrated circuits.

LT1761ES5-3#TRPBF is a compact, low-dropout regulator. Typical application areas include:
- Battery-powered portable devices needing low quiescent current
- Microcontroller, DSP, and FPGA supply rails requiring stable voltages
- Post-regulation for switching supplies to improve noise and transient response
- Sensor and instrumentation front-ends and precision analog circuits
- USB and telecom/industrial electronics requiring a compact, efficient LDO
- Any space-constrained design needing a fixed or adjustable local regulator with good line/load regulation and stability with ceramic caps
