The Integrated Voltage Regulator (LDO)

The TIOS1023 and TIOS1025 each have an integrated linear voltage regulator (LDO) which can supply power to external components. The voltage regulator is specified for VCC voltages in the range of 7 V to 36 V (TIOS1025) or in the range of 5 V to 36 V (TIOS102, TIOS1023) with respect to GND. The LDO is capable of delivering up to 20 mA. The LDO output is current limited to 35-mA to limit the inrush current onto VCC_OUT decoupling capacitors during initial power up.

In the DSBGA (YAH) package, TIOS1023L offers pin-configurable LDO output via VSEL pin. When VSEL is connected to GND, VCC_OUT is configured to provide a 5-V output. When VSEL is left floating, VCC_OUT provides a 3.3-V output.

The LDO is designed to be stable with standard ceramic capacitors with values of 1 μF or larger at the output. X5R- and X7R-type capacitors are best because they have minimal variation in value and ESR over temperature. Maximum ESR should be less than 1 Ω. With tolerance and dc bias effects, the minimum capacitance to ensure stability is 1 μF.
