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

Select this component when a compact footprint is prioritized over higher current capabilities. The U-DFN2020-6 package offers space savings compared to traditional SOT packages but requires adequate copper area for thermal dissipation. Evaluate the 150mA limit against peak load demands to prevent triggering internal current limits. Consider the wide input voltage range suitability for direct battery connection without intermediate regulation stages.
