Introduction

Analogue Devices (ADI) ADP1762ACPZ-0.9-R7 voltage regulator is one of the linear voltage regulators from the Analog Devices family with a compact miniature SOT-23 package. The device is capable of supplying 0.9V to 100mA for a wide range of applications. It consists of an internal voltage reference and N-channel mosfet. The mosfet is configured as a high-side switch, with the voltage input connected to the source and the ground connected to the drain. The internal voltage source provides a highly accurate reference voltage with a tolerance of ±5mV.

Application Field and Working Principle

ADP1762ACPZ-0.9-R7 is designed to be used in a wide variety of applications such as general purpose microcontroller power supplies, voltage regulation of industrial motor drives, portable power supplies, and many other industrial and automotive applications. The device is capable of operating over a wide range of input voltages ranging from 2.7V to 16.5V. The internal N-channel mosfet operates as a high-side switch, which allows the device to convert the voltage input to a regulated output voltage. The device has a Maximum Regulated Voltage of 0.9V and a Maximum Ripple Voltage of maximum 5mV. The device also has Thermal Regulation of maximum 2.5%. This allows the device to regulate the output voltage with high precision and accuracy. The device also has a shutdown and Over-Temperature Protection (OTP). This ensures safe and reliable operation in harsh environmental conditions, such as those found in automotive and industrial applications. The OTP is also used to prevent the device from overload and overvoltage conditions.The device also has a low quiescent current of 0.8uA, which reduces the power wastage in the system. Additionally, the device also includes an Internal Soft-Start feature that limits the inrush current when the device is powered up.
