DESCRIPTION

The APE8805A is a low dropout, positive linear regu- lator with very low quiescent current. The APE8805A can supply 600mA output current with low dropout voltage at about 600mV. The BP pin with a 10nF bypass capacitor can help reduce the output noise level. The shutdown function can provide remote control for the external signal to decide the on/off state of APE8805A. With a logic high level at SHDN pin, the device is in the on state, and vice versa. The APE8805A regulator is able to operate with output capacitors as small as 1µF for stability. Other than the current limit protection, APE8805A also offers the on chip thermal shutdown feature providing protection against overload or any condition when the ambient temperature exceeds the maximum junction tempe- rature. The APE8805A offers high precision output voltage of ± 2%. It is available in fixed output voltages including The APE8805A is housed in low-profile, space-saving 5-lead SOT-23 package.

APPLICATION INFORMATION

The APE8805A is a low dropout linear regulator that could provide 600mA output current at dropout volt- age about 600mV. Current limit and on chip thermal shutdown features provide protection against any combination of overload or ambient temperature that could exceed maximum junction temperature. 1. Output and Input Capacitor The APE8805A regulator is designed to be stable with a wide range of output capacitors. The ESR of the output capacitor affects stability. Larger value of the output capacitor decreases the peak deviations and improves transient response for larger current changes. The capacitor types (aluminum, ceramic, and tant- alum) have different characterizations such as temperature and voltage coefficients. All ceramic capacitors are manufactured with a variety of dielectrics, each with different behavior across temperature and applications. Common dielectrics used are X5R, X7R and Y5V. It is recommended to use 1uF to 10uF X5R or X7R dielectric ceramic capacitors with 30mΩ to 50mΩ ESR range betw- een device outputs and ground for stability. The APE8805A is designed to be stable with low ESR ceramic capacitors and higher values of ca- pacitors and ESR could improve output stability. The ESR of output capacitor is very important because it generates a zero to provide phase lead for loop stability. There are no requirements for the ESR on the input capacitor, but its voltage and temperature coefficient have to be considered for device application environment. 2. Protection Features In order to prevent overloading or thermal con- dition from damaging the device, APE8805A has internal thermal and current limiting functions designed to protect the device. It will rapidly shut off PMOS pass element during overload- ing or over temperature condition. 3. Thermal Consideration The power handling capability of the device will be limited by maximum operation junction temperature. The power dissipated by the device will be estimated by PD = IOUT × (VIN-VOUT). The power dissipation should be lower than the maximum power dissipation listed in “Absolute Maximum Ratings” section. 4. Shutdown Operation The APE8805A is shutdown by pulling the SHDN input low, and turned on by driving the SHDN high. If this function is not used, the SHDN input should be tied to VIN to keep the regu- lator on at all times (the SHDN must not be left floating). Advanced Power Electronics Corp.
