With this structure a very low dropout voltage at current up to 150 mA is obtained. The output voltage is regulated up to input supply voltage of 40 V. The high-precision of the output voltage (2%) is obtained with a pre-trimmed reference voltage. The voltage regulator automatically adapts its own quiescent current to the output current level. In light-load conditions the quiescent current goes to 55 A only (low consumption mode). This procedure features a certain hysteresis on the output current (see Figure 6). Short-circuit protection to GND and a thermal shutdown are provided. Figure 14. Application schematic 9%$77 9R 9V & /%1 & Co &R *1' *$3*36 The input capacitor C1 100 F is necessary as backup supply for negative pulses which may occur on the line. The second input capacitor C2 220 nF is needed when the C1 is too distant from the VS pin and it compensates smooth line disturbances. The C0 ceramic capacitor, connected to the output pin, is for bypassing to GND the high-frequency noise and it guarantees stability even during sudden line and load variations. Suggested value is C0 = 220 nF with ESR 100 m. Stability region is reported in Figure 15. 10/21 DS6183 Rev 11 L5150BN Electrical specifications Figure 15.
