Description

The LT1763MPDE is a low-dropout (LDO) linear voltage regulator manufactured by Analog Devices. It is designed to provide a stable output voltage with low noise and minimal dropout voltage, making it suitable for applications requiring precise voltage regulation. The device operates with an input voltage range of 1.8V to 20V and can output up to 1A of current.
Key features include an output voltage accuracy of ±1%, low quiescent current, and a shutdown mode that reduces power consumption. The LT1763 is available in various fixed output voltage options, including 3.3V and 5V. Its compact size and thermal performance make it ideal for portable devices, RF applications, and IoT devices.
The device also includes built-in protection features such as overcurrent protection and thermal shutdown, enhancing reliability in critical applications. Overall, the LT1763MPDE is a versatile choice for designers seeking efficient power management solutions in space-constrained environments.

Features

The LT1763MPDE is a low noise, low dropout (LDO) voltage regulator from Analog Devices. Key features include:
1. Output Voltage: Fixed output voltages of 1.2V, 1.5V, 1.8V, 2.5V, 3.0V, and 3.3V.
2. Dropout Voltage: Very low dropout voltage (typically 300mV at 100mA load), enabling it to maintain regulation with minimal input-output voltage differential.
3. Low Noise: Provides low output noise (typical 20µVRMS), making it suitable for sensitive applications.
4. High PSRR: Excellent power supply rejection ratio (PSRR) which maintains stable output despite fluctuations in the input voltage.
5. Load and Line Regulation: Superior load regulation (typically 0.1%) and line regulation (typically 0.01%/V).
6. Thermal Protection: Built-in thermal shutdown feature for safe operation under high load conditions.
7. Compact Package: Available in a small 8-lead MSOP package, ideal for space-constrained applications.
These features make the LT1763MPDE suitable for powering sensitive analog circuits, RF applications, and portable devices.

Package

The LT1763MPDE is packaged in a 5-lead TSOT-23 (Thin SOT-23) package type.

Pinout

The LT1763MPDE is a low dropout linear regulator (LDO) from Analog Devices. It comes in a 5-lead SOT-23 package, which has a pin count of 5.
The pin functions are as follows:
