LT3021ES8-1.2#PBF

LT3021ES8-1.2#PBF is a fixed-output low-dropout regulator from Linear Technology (now Analog Devices). The ES8 suffix denotes the 8‑pin Pb-free package; #PBF confirms Pb-free RoHS compliance. It provides a fixed 1.2 V output for supplying core/memory rails and other low-voltage domains. Benefits typically include low dropout, good line/load regulation, low quiescent current, fast transient response, and common regulator protections (overload/thermal shutdown). Use it with proper input decoupling and an output capacitor as specified in the datasheet. For exact electrical specs (input voltage range, dropout, max load, quiescent current, and pinout), consult the LT3021 datasheet and the -1.2 ES8 ordering information.

LT3021ES8-1.2#PBF is a fixed 1.2 V LDO. There isn’t a single direct drop‑in cross reference; equivalents depend on current and package. Possible 1.2 V fixed LDO substitutes from other suppliers include Microchip MCP1700-1.2, ST LP2985-1.2, and TI TLV70012 (or TLV700 family). Always confirm dropout, quiescent current, and package footprint against your design.

LT3021ES8-1.2#PBF features (concise):
- 1.2 V fixed output version (ES8 package)
- 8‑lead ES8 Pb‑free (PBF) package for RoHS compliance
- Very low quiescent current (micropower operation)
- Low dropout voltage for operation with modest Vin headroom
- Good line and load regulation; low output noise
- Built‑in protection: overcurrent/short‑circuit protection and thermal shutdown
- Reverse-current protection from output to input
- Suitable for battery-powered and portable applications
Note: For exact electrical specs (input range, dropout, current limit, PSRR, temp range, etc.), please refer to the LT3021/E datasheet.

Pin count: 8 pins (ES8 package).
Function: Fixed-output low-dropout regulator (LDO) with 1.2 V output; includes an enable/shutdown input and a bypass/bias option in the ES8 package. PBF indicates RoHS-compliant lead-free package.

Analog Devices, Inc. (ADI). It’s a multinational semiconductor company that designs and manufactures analog, mixed-signal, and DSP integrated circuits. The LT prefix denotes Linear Technology’s lineage, now part of ADI after its acquisition.

LT3021ES8-1.2#PBF is a fixed 1.2 V low-dropout regulator in an 8‑pin ES8 package. Typical application areas:
- Battery-powered devices (wearables, sensors, IoT)
- Core rails for microprocessors/SoCs and memory requiring 1.2 V
- RF/analog front-ends and ADC/DAC reference supplies
- Portable instrumentation and medical devices
- Space-constrained multi-rail power designs
- Post-regulation to improve PSRR/noise in mixed-signal systems
