The ADP3336 operates with an input voltage range of 2.6 V to 12 V and delivers a continuous load current up to 500 mA. The ADP3336 stands out from conventional LDOs with the lowest thermal resistance of any MSOP-8 package and an enhanced process that enables it to offer performance advantages beyond its competition. Its patented design requires only a 1.0 µF output capacitor for stability. This device is insensitive to output capacitor Equiva- lent Series Resistance (ESR), and is stable with any good quality capacitor, including ceramic (MLCC) types for space- restricted applications. The ADP3336 achieves exceptional accuracy of ±0.9% at room temperature and ±1.8% over tem- perature, line, and load. The dropout voltage of the ADP3336 is only 200 mV (typical) at 500 mA. This device also includes a safety current limit, thermal overload protection and a shutdown feature. In shutdown mode, the ground current is reduced to less than 1 µA. The ADP3336 has ultralow quiescent current 80 µA (typical) in light load situations. COUT 1 F ADP3336 OUT VIN IN GND VOUT FB ON OFF IN OUT OUT R1 R2 SD CIN 1 F Figure 1.
