TPS735xx SBVS087K – JUNE 2008 – REVISED AUGUST 2013 www.ti.com APPLICATION INFORMATION The TPS735xx family of LDO regulators combines the high performance required of many RF and precision analog applications with ultra-low current consumption. High PSRR is provided by a high gain, high bandwidth error loop with good supply rejection at very low headroom (VIN – VOUT).

TPS735xx www.ti.com optimize noise, equivalent series resistance of the output capacitor can be set to approximately 0.2Ω. This configuration maximizes phase margin in the control loop, reducing total output noise by up to 10%. Noise can be referred to the feedback point (FB pin) such that with CNR = 0.

TPS735xx SBVS087K – JUNE 2008 – REVISED AUGUST 2013 www.ti.com approximately 50μA. In typical applications, the junction cannot reach high temperatures at light loads because there is no appreciable dissipated power. The specified ground current would then be valid at no load in most applications. Power dissipation depends on input voltage and load conditions.

TPS735xx www.ti.com SBVS087K – JUNE 2008 – REVISED AUGUST 2013 NOTE: When the device is mounted on an application PCB, it is strongly recommended to use ΨJT and ΨJB, as explained in the Estimating Junction Temperature section. ESTIMATING JUNCTION TEMPERATURE Using the thermal metrics ΨJT and ΨJB, as shown in the Thermal Information table, the junction temperature can be estimated with corresponding formulas (given in Equation 4). For backwards compatibility, an older θJC,Top parameter is listed as well.
