Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when a fixed 1.0V output is required without external resistor networks. Consider its 150mA current capability against the peak load demands of the target circuit. Evaluate the thermal performance based on the expected ambient temperature and PCB copper area, as the TSOT-23-5 package has limited heat dissipation. Compare the PSRR and noise characteristics against other LDOs if the application is sensitive to power supply ripple.
