Description

NCP511SN33T1G is ON Semiconductor’s fixed-threshold 3.3 V microcontroller supervisor (voltage detector). It monitors the supply (Vcc) and generates a reset signal to ensure a MCU starts in a known state and remains reset during brownouts or power-up/down.
Key points
- Fixed 3.3 V threshold; single-supply operation
- Reset output is active-low (RESET#) and typically drives the MCU reset pin directly
- Fast response with built-in power-on reset timing
- Very low quiescent current; packaged in a small SOT-23/SC-70 variant (T1G)
- Ideal for simple, watchdog-free MCU/processor reset in embedded systems
Usage notes
- Connect Vcc, GND, and the RESET# line to your MCU (with any needed pull-up per MCU requirements)
- Check the datasheet for exact electrical specs, hysteresis, and timing to match your application
If you want exact figures (threshold tolerance, delay, current, etc.), I can pull the datasheet details.

Features

Here are the typical features of NCP511SN33T1G (ON Semiconductor):
- Fixed 3.3 V output LDO regulator
- Very small footprint (SOT-23-3 style) and RoHS-compliant
- Enable (EN) input to turn the regulator on/off
- Low quiescent current for battery-powered applications
- Overcurrent/short-circuit protection and thermal shutdown
- Stable with ceramic output capacitors
- Good line and load regulation with fast transient response
- Suitable for powering microcontrollers and digital logic rails in compact designs
Note: For exact electrical specs (input range, dropout, current limit, quiescent current values, etc.), please consult the official datasheet.

Package

SOT-23-3 (SC-70-3) package; 3-pin, lead-free (green) variant.

Pinout

- Pin count: 5 pins (SOT-23-5/SC-70-5 package)
- Function: Fixed 3.3 V low-dropout regulator with an enable/shutdown input
Typical pinout (pin 1–5): EN, GND, VOUT, VIN, NC (No Connect). Note: verify exact pin assignment in the datasheet for your package variant.

Manufacturer

- Manufacturer: ON Semiconductor (ON Semiconductor Corporation).
- What kind of company: A global American semiconductor company, headquartered in Phoenix, Arizona, that designs and manufactures energy‑efficient power management ICs, analog devices, discretes, sensors, and related components for automotive, industrial, and consumer markets.

Application
