Using process with a PNP pass element, these regulator s feature 350mV (full load) dropout voltages and very low ground current. These devices also find applications in lower current, low dropout-critical systems, where their tiny dropout voltage and ground current values are important attributes. The LM27150, LM27151 and LM27152 are fully protected a gainst over current faults, reversed input polarity, reversed lead insertion, over temperature opera tion, and positive and negative transient voltage spikes. LM27151 features logic level enable control and an error flag which signals whenever the output falls out of regulation.

APPLICATION INFORMATION
The LM27150 are high performance low-dropout voltage regulators suitable for all moderate to high current voltage regulator applications. Their 350mV dropout vo ltage at full load makes them especially valuable in battery powered systems and as high efficiency noise f ilters in "post-regulator" applications. Unlike older NPN-pass transistor designs, dropout performance of the PNP output of these devices is limited merely by the low VCE saturation voltage. The LM27150 family of regulators is fully protected fr om damage due to fault conditions. Current Limiting is provided. This limiting is linear; output current under overload conditions is constant. Thermal shutdown disables the device when the die temperature exceeds the 125 ℃ maximum safe operating temperature. Transient protection allows device survival even w hen the input voltage spikes between -20V and +30V. When the input voltage exceeds about 28V, the over voltage sensor temporarily disables the regulator. VIN OUT GND VOUT VIN COUT CIN Figure 1. Linear regulators require only two capacitors for operation. Where TJMAX ≤ 125℃ and CSθ is between 0 and 2℃/W.
