The ADP3308 is a member of the ADP330x family of precision
low dropout anyCAP voltage regulators. It is pin-for-pin and
functionally compatible with National’s LP2980, but offers
performance advantages. The ADP3308 stands out from the
conventional LDOs with a novel architecture and an enhanced
process. Its patented design requires only a 0.47
µF
output
capacitor for stability. This device is stable with any type of
capacitor regardless of its ESR (Equivalent Serial Resistance)
value, including ceramic types for space restricted applications.
The ADP3308 achieves
±
1.2% accuracy at room temperature
and
±
2.2% overall accuracy over temperature, line and load
regulations. The dropout voltage of the ADP3308 is only
80 mV (typical) at 50 mA. This device also includes a current
limit and a shutdown feature. In shutdown mode, the ground
current is reduced to ~1
µA.
The ADP3308 operates with a wide input voltage range from
3.0 V to 12 V and delivers a load current in excess of 100 mA.
The ADP3308 anyCAP LDO offers a wide range of output
voltages. For 100 mA version, refer to the ADP3309 data sheet.
