Description

The LT3032IDE#PBF is a low-dropout (LDO) linear regulator manufactured by Analog Devices. It is a dual-channel, low-noise, positive and negative voltage regulator designed for applications requiring both positive and negative supply voltages. The device offers a wide input voltage range and can supply output currents up to 150mA for each channel, making it suitable for a variety of applications including powering analog and mixed-signal systems.
One of the key features of the LT3032 is its low dropout voltage, which is essential for maintaining regulation with minimal input-to-output voltage differential. It also boasts low output noise and high power supply rejection ratio (PSRR), making it ideal for noise-sensitive applications.
The "IDE" in the part number indicates the industrial temperature range, while "#PBF" suggests that the product is lead-free (RoHS compliant). This regulator is typically used in precision instruments, audio equipment, and communication systems, where stable and clean voltage rails are critical. The device is packaged in a compact 16-lead, 3mm x 5mm DFN package, which saves board space.

Features

The LT3032IDE#PBF is a dual-channel, low-dropout (LDO) linear regulator from Analog Devices. It is designed to provide positive and negative output voltages. Key features include:
1. Dual Output: Can deliver up to 150 mA of output current per channel, one positive and one negative voltage output.
2. Low Dropout Voltage: Typically around 300 mV at full load, which enhances efficiency.
3. Low Noise: Offers low output noise (20 µVRMS over 10 Hz to 100 kHz) and high Power Supply Rejection Ratio (PSRR), making it suitable for noise-sensitive applications.
4. Wide Input Voltage Range: Operates from 1.7V to 20V for the positive output and -1.7V to -20V for the negative output.
5. Adjustable Output Voltage: Both outputs can be adjusted through external resistor dividers.
6. Protection Features: Includes current limiting and thermal shutdown for reliability.
7. Package: Available in a thermally enhanced 16-lead, 4mm × 4mm DFN package or a 16-lead, thermally enhanced TSSOP package.
These features make the LT3032IDE#PBF suitable for applications requiring dual power rails with low noise and high precision.

Pinout

The LT3032IDE#PBF is a dual linear regulator from Analog Devices designed to provide low dropout voltage regulation with positive and negative output voltages. It comes in a 16-pin package, specifically a thermally enhanced 16-lead (5mm x 3mm) DFN (Dual Flat No-leads) package.
Key features include a low dropout voltage of 300mV at full load, output current capability of 150mA for both positive and negative outputs, and a wide input voltage range. The positive output voltage can be adjusted from 1.22V to 20V, while the negative output can be set from -1.22V to -20V.
The LT3032 is designed for high performance in terms of low noise, high PSRR (Power Supply Rejection Ratio), and excellent line and load regulation. These characteristics make it suitable for applications requiring dual polarity power supplies, such as op-amp and data converter circuits.
