TPS73512QDRBRQ1

具有使能功能的汽车类 500mA、低噪声、低 IQ、低压降稳压器 8-SON -40 to 125

Description

The TPS735-Q1 family of low-dropout LDO, low power linear regulators offers excellent ac performance with very low ground current. High power-supply rejection ratio PSRR, low noise, fast start-up, and excellent line and load transient responses are provided while consuming a very low 46 μA typical ground current.

The TPS735-Q1 family of devices is stable with ceramic capacitors and uses an advanced BiCMOS fabrication process to yield a typical dropout voltage of 280 mV at 500-mA output. The TPS735-Q1 family of devices uses a precision voltage reference and feedback loop to achieve overall accuracy of 2% VOUT > 2.2 V over all load, line, process, and temperature variations. This family of devices is fully specified from TA = –40°C to 125°C and is offered in a low-profile, 3-mm × 3-mm SON package.
