●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.
