FAQs

What is LP3965EMP-ADJ?

The LP3965EMP-ADJ is a high-performance, low dropout voltage regulator (LDO) manufactured by Texas Instruments. It is designed to provide a regulated output voltage with a low dropout voltage, making it ideal for applications requiring a stable power supply in low input-to-output voltage configurations.

How Does LP3965EMP-ADJ Work?

The LP3965EMP-ADJ works by accepting an input voltage and regulating it to a stable output voltage with low dropout. It utilizes a precision voltage reference, error correction circuitry, and a series pass element to achieve the desired output voltage regardless of input fluctuations. The LDO is capable of delivering high current with low noise and good line/load transient response.

How Many Pins does LP3965EMP-ADJ have and What are the Functions of the Pinout Configuration?

The LP3965EMP-ADJ is available in a 8-pin PWP (PowerPAD) package. The pinout configuration includes:

VIN: Input voltage pin.
GND: Ground pin.
EN: Enable pin to control the regulator's operation.
FLT: Fault indicator for over-temperature or over-current conditions.
ADJ: Adjust pin for setting the output voltage.
VOUT: Regulated output voltage pin.

What are the Pros and Cons of LP3965EMP-ADJ?

Pros:

Low Dropout Voltage: Enables stable regulation even when the input voltage is close to the output voltage.
High Current Capability: Capable of delivering high output currents, suitable for power-hungry loads.
Low Noise: Provides a clean and stable output voltage for noise-sensitive applications.
Thermal Shutdown and Over-Current Protection: Enhances system reliability and safety.
Small Package: The 8-pin PWP package offers space-efficient integration.

Cons:

Heat Dissipation: May require a heat sink or careful thermal design in high-power applications.
Cost: Higher dropout voltage LDOs may be available at lower cost for less demanding applications.
External Capacitors: Requires external capacitors for stability and noise filtering.

Are There Any Equivalents/Alternatives to LP3965EMP-ADJ for Recommendation?

The LT1765 from Analog Devices is a comparable high-performance LDO with similar features.
