TPL920 Series

2-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 TPL920 series products are 2-A high-current, 6-μV_RMSlow-

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

110-mV ultra-low dropout voltage at 2-A load condition. The

TPL920 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

2A Maximum Output Current

◼

Low Dropout Voltage: 110 mV typ at 2 A

High PSRR:

◆

70dB at 1kHz

40dB at 1MHz

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

makes the TPL920 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 TPL920 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 22 μF or Larger Ceramic Output Capacitor

Thermal Shutdown and Over-Current Protection

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

Package Options:

◆

5×5 QFN-20

The TPL920 series products provide 5×5 QFN-20 package with

guaranteed operating junction temperature range (T_J) from –

40°C to +125°C.
