LT1963ES8-3.3#PBF

The LT1963ES8-3.3#PBF is a fixed 3.3V low-dropout regulator (LDO) from Linear Technology (now Analog Devices). It comes in an 8‑pin ES8 Pb‑free package and is intended to provide a clean, stable 3.3V supply for microcontrollers, logic, and analog front‑ends.
Key points:
- Fixed output: 3.3V
- Simple input-to-output regulation with an enable/shutdown option
- Protection features typical of LT regulators (short‑circuit/current limit, thermal/shutdown protection, and reverse‑polarity protection)
- Pb-free (PBF) and space‑efficient ES8 package
How to use:
- VIN → input supply (above 3.3V)
- VOUT → 3.3V rail
- GND → system ground
- EN (if present) to enable the device (often tied to VIN for always-on)
Applications include microcontroller and FPGA peripheral power, ASIC/ADC/DAC front-ends, and compact portable electronics. For exact electrical specs, pinout, and application notes, see the LT1963ES8-3.3#PBF datasheet.

LT1963ES8-3.3#PBF features (fixed 3.3V LDO in Pb-free package):
- Fixed 3.3V output in an 8-pin ES8 Pb-free package (PBF)
- Wide input voltage range with low dropout
- Enable/shutdown input to disable output
- Internal current limit and thermal shutdown protection
- Short-circuit/overload protection with safe operating behavior
- Reverse-current/reverse-battery protection
- Low-noise, good power-supply rejection (PSRR) and stable regulation
Note: For exact electrical specs (voltage ranges, currents, quiescent current, etc.), please consult the official datasheet.

- Pin count: 8 pins (ES8 package, MSOP8).
- Function: Fixed-output low-dropout linear regulator (3.3V) with enable/shutdown control.
