DUAL 150MA HIGH PERFORMANCE MOBILE LDOTM IN SOT23-6L
FSP2150
FEATURES
180mV Typical Dropout with 150mA Load 2.0% Voltage Accuracy High PSRR: 70dB@100Hz Low noise output Current Limit Thermal Shutdown Protection Short Circuit Protection Very small SOT23-6L Package
GENERAL DESCRIPTION
The dual LDO FSP2150 series of positive voltage linear regulators feature high output voltage accuracy, low quiescent current and low dropout voltage, making them ideal for battery powered applications. The line transient response and load transient response are excellent. Their high PSRR make them useful in applications where AC noise on the input power supply must be suppressed. Space-saving SOT23-6L package for 2ch LDOs is attractive for portable and handheld applications. They have both thermal shutdown and a current limit feature to prevent device failure under extreme operating conditions. They are stable with an output capacitance of 2.2uF or greater.

APPLICATION INFORMATION
Capacitor Selection and Regulator Stability Similar to any low dropout regulator, the external capacitors used with the FSP2150 must be carefully selected for regulator stability and performance. Using a capacitor, CIN, whose value is2.2F at the FSP2150 input pin, the amount of the capacitance can be increased without limit. Please note that the distance between CIN and the input pin of the FSP2150 should not exceed 0.5 inch. Ceramic capacitors are suitable for the FSP2150. Capacitors with larger values and lower ESR provide better PSRR and line-transient response. The FSP2150 is designed specifically to work with low ESR ceramic output capacitors in order to save space and improve performance. Using an output ceramic capacitor whose value is 2.2F with ESR5m ensure stability. Shutdown Input Operation The FSP2150 is shutdown by pulling the EN input low, and is turned on by tying the EN input to VIN or leaving the EN input floating. Dropout Voltage A regulator's minimum dropout voltage determines the lowest usable supply voltage. The FSP2150 has a typical 180mV dropout voltage. In battery powered systems, this will determine the useful end-of-life battery voltage. Current Limit and Short Circuit Protection The FSP2150 features a current limit, which monitors and controls the gate voltage of the pass transistor. The output current can be limited to 300mA by regulating the gate voltage. The FSP2150 also has a built-in short circuit current limit.
