QPM018B-B AME, Inc. AME8750 Low-Dropout 150mA / 150mA Dual CMOS Regulator n General Description The AME8750 dual, low dropout, linear regulators operate from higher VOUT+VDROPOUT to 5.5V input and deliver up to 150mA / 150mA output current each. It has a bypass pin option allows users to decouple the bandgap reference for reducing the output noise. Low dropout voltage and low quiescent current(70µA typ.) make them ideal for battery applications. The AME8750 is available with a wide variety of voltage options as standard and can be trimmed to 1.5% accuracy. For protection purpose, AME8750 has thermal shutdown to prevent device failure under the “worst” operating conditions. n Features l Very Low Dropout Voltage l Guaranteed 150mA / 150mA Each Output n Functional Block Diagram EN1 ON/OFF Control Current Limit Error Amp1 VOUT1 VR1 Each Circuit R11 R12 VIN GND Current Limit Error Amp2 VOUT2 VR2 Each Circuit EN2 R21 Voltage Reference ON/OFF Control R22 n Typical Applications AME8750AEEY VIN IN l Accurate to Within 1.5% For Both Outputs VOUT1 OUT1 EN AME8750 l Typical 70 µA Quiescent Current VOUT2 OUT2 BYP l Over-Temperature Shutdown GND l Current Limiting l Noise Reduction Bypass Cap 1µF 1µF 10nF 1µF l Power-Saving Shutdwon Mode l All AME's Lead Free Product Meet RoHS Standards AME8750BEEY / AME8750AEVA n Applications VIN VOUT1 OUT1 IN l Cellular Phones EN1 l Palm / Notebook EN2 AME8750 VOUT2 OUT2 GND l Battery Power Equipment l Handheld Widgets 1µF Rev.E.01 1µF 1µF 1 AME, Inc.

E.01 AME, Inc. AME8750 Low-Dropout 150mA / 150mA Dual CMOS Regulator n Detailed Description The AME8750 is low-dropout, low quiescent-current linear regulator designed primarily for battery-powered applications. These parts are available with preset output voltage ranging from 1.8V to 3.3V, and the parts can supply loads up to 150mA. Shutdown AME8750AEEY The AME8750AEEY has a single shutdown control input(EN). Drive EN low to shut down both outputs, reducing supply current to 0.3µA. Connect EN to a logic-high, or IN, for normal operation. AME8750BEEY/AME8750AEVA The AME8750BEEY/AME8750AEVA have independent shutdown control inputs (EN1 and EN2). Drive EN1 low to shutdown VOUT1. Drive EN2 low to shut down VOUT2. Drive both EN1 and EN2 low to shut down the entire chip, reducing supply current to 0.3µA. Connect both EN1 and EN2 to a logic-high, or IN, for normal operation. n Application Information Capacitor Selection and Regulator Stability Use a 1µF capacitor on the AME8750 input and a 1µF capacitor on the outputs. Larger input capacitor values and lower ESRs provide better supply noise rejection and line transient response. PSRR and Operation from Sources Other than Batteries The AME8750 is designed to deliver low dropout voltages and low quiescent current in battery powered systems. Power-supply rejection is 54dB at low frequencies. (See the PSRR vs. Frequency graph) Internal P-Channel Pass Transistor The AME8750 features two 1Ω P-Channel MOSFET pass transistors. A P-Channel MOSEFT provides several advantages over similar designs using PNP pass transistors, including longer battery life. It requires no base drive, which reduces quiescent current significantly. The AME8750 only consumes 70µA of quiescent current whether in dropout, light-load, or heavy-load applications. Current Limit The AME8750 contains two independent current limiters, one for each regulator, which monitor and control the pass transistor’s gate voltage, limiting the guaranteed maximum output current to 180mA minimum. The output can be shorted to ground for an indefinite time without damaging the part. Thermal-Overload Protection Thermal -overload protection limits total power dissipation in the AME8750. When the junction temperature exceeds TJ=150oC, the thermal sensor signals the shutdown logic, turning off the pass transistor and allowing the IC to cool. Rev.E.01 9 AME, Inc.
