NCP730ASNADJT1G

NCP730ASNADJT1G is ON Semiconductor’s adjustable low‑dropout (LDO) voltage regulator. The “ADJ” in the name indicates the output voltage is set by an external resistor divider, giving flexibility to generate a specific rail voltage from a higher input. The “1G” suffix denotes RoHS-compliant (green) packaging in a tape‑and‑reel format. This device is used to power microcontrollers, sensors, and other small-load circuits in compact, portable electronics where a stable DC rail is needed from a higher Vin. It’s designed with typical LDO protections such as current limit and thermal shutdown to guard against overloads. The exact pinout, voltage range, maximum output current, dropout, and protection features vary by package and variant, so consult the official datasheet for NCP730ASNADJT1G to confirm electrical specs, recommended operating conditions, and application circuits.

Here are the typical features of the NCP730ASNADJT1G (ON Semiconductor):
- Adjustable output voltage via external resistor divider (ADJ version)
- Enable/shutdown control
- Low quiescent current (suitable for battery-powered applications)
- Low dropout regulator for efficient operation
- Accurate output with good line and load regulation
- Protective circuitry: overcurrent/short-circuit protection
- Thermal shutdown protection
- Small footprint package suitable for compact designs
Note: Exact electrical specs (input voltage range, dropout voltage, max output current, temperature range, tolerance) vary by variant. Please consult the official datasheet for precise numbers and conditions for NCP730ASNADJT1G.

Pin count: 5 pins.
Function: NCP730ASNADJT1G is a microprocessor supervisory/voltage detector IC with an adjustable threshold. It monitors VDD and asserts a reset signal to a microcontroller when the supply falls below the set threshold (power-on/power-down reset).

- Manufacturer: ON Semiconductor (ON Semi).
- Company type: A global semiconductor company that designs and manufactures energy-efficient integrated circuits (ICs), including power management, analog, and sensor devices.

NCP730ASNADJT1G is a voltage supervisor/reset IC. Typical application areas:
- Microcontroller/processor reset supervision (power-on reset and brown-out protection)
- Reset control for digital ICs (FPGA/CPLD, ASICs)
- Battery-powered and low-power embedded systems
- Consumer electronics, data acquisition, and communications equipment
- Automotive and industrial electronics requiring reliable reset during power-up/power-down
It provides a clean reset signal when Vcc falls below a threshold, protecting proper device startup and operation.
