TPL930 Series

3-A Output, High-PSRR, Low-Noise LDO Regulator

Features

Applications

◼

Input Voltage Range:

◼

Wireless Communication: CPU, ASIC, FPGA, CPLD, DSP

High-Performance Analog: ADC, DAC, LVDS, VCO

Noise-Sensitive Imaging: CMOS Sensors, Video ASICs

◆

Without BIAS: 1.4 V to 6.5 V

With BIAS: 1.1 V to 6.5V

Output Voltage Options:

Description

◆

Fixed Output Voltage: 0.8 V to 3.95 V

Adjustable Output Voltage: 0.8 V to 5.2 V

The TPL930 series products are 3-A high-current, 6-μV_RMSlow-

noise, high-PSRR, high-accuracy linear regulators with typically

145-mV ultra-low dropout voltage. The TPL930 series products

support both fixed output voltage ranges from 0.8 V to 3.95 V

and adjustable output voltage ranges from 0.8 V to 5.2 V with

external resistor divider.

±1% Output Accuracy Over Line, Load Regulation, and

Operating Temperature Range With BIAS

3A Maximum Output Current

◼

Low Dropout Voltage: 145 mV typ at 3 A

High PSRR:

◆

70dB at 1kHz

40dB at 1MHz

Ultra-low noise, high PSRR, and high output current capability

makes the TPL930 series products ideal power supply for noise-

sensitive applications, such as high-speed communication

facilities, test and measurement devices, or high-definition

imaging equipment. Accurate output voltage tolerance, output

voltage remote sensing, excellent transient response, and

adjustable soft-start control ensures the TPL930 series products

optimal power supply for the large-scale processors or digital

loads, such as ASIC, FPGA, CPLD and DSP.

◼

6 μV_RMSOutput Voltage Noise

Excellent Transient Response

Enable and Adjustable Soft-Start Control

Open-Drain Power-Good (PG) Output

Stable with a 47 μF or Larger Ceramic Output Capacitor

Thermal Shutdown and Over-Current Protection

Operating Junction Temperature: –40°C to +125°C

Package Options:

◆

3.5×3.5 QFN-20

The TPL930 series products provide 3.5×3.5 QFN-20 package

with guaranteed operating junction temperature range (T_J) from

–40°C to +125°C.
