Description

The TPS72710 family of low-dropout (LDO) linear regulators are ultralow quiescent current LDOs with excellent line and ultra-fast load transient performance and are designed for power-sensitive applications. The LDO output voltage level is preset by the use of innovative factory EEPROM programming. A precision bandgap and error amplifier provides overall 2% accuracy over load, line, and temperature extremes. The TPS727xx family is available in 1,5-mm x 1,5-mm SON and wafer chip-scale (WCSP) packages that make it ideal for handheld applications. This family of devices is fully specified over a temperature range of TJ = –40°C to +125°C.

Features

1. Very Low Dropout :

(1) 65 mV Typical at 100 mA

(2) 130 mV Typical at 200 mA

(3) 163 mV Typical at 250 mA

2. Excellent Load Transient Performance

3. High PSRR: 70 dB at 1 kHz

Description

The LM317T are adjustable 3-terminal positive-voltage regulators capable of supplying 1.5A over a differential voltage range of 3V to 40V. They are exceptionally easy to use and require only two external resistors to set the output voltage. Both input and output regulation is better than standard fixed regulators. In addition to higher performance than fixed regulators, these regulators offer full overload protection available only in integrated circuits. Included on the chip are current limit, thermal overload protection, and safe-area protection.

Features

1. Output Voltage Range Adjustable from 1.2 V to 37V
2. Output Current Capability of 1.5A Max
3. Input Regulation Typically 0.01% Per Input-Volt Change
4. Output Regulation Typically 0.1%
5. Peak Output Current Constant over Temperature Range of Regulator
6. Popular 3-Lead TO-220 AB Package
