AMC7637
ULTRA LOW I_Q
300mA LOW DROPOUT REGULATOR
DESCRIPTION
FEATURES
The AMC7637 is an ultra low quiescent current, and
low dropout regulator rated for 300mA output current. The
low power consumption and high accuracy is achieved
through CMOS technology and internal trimmed reference
voltage.
The AMC7637 consists of a high-precision voltage
reference, error correction circuit, and a current limit output
driver. The fast transient response is an outstanding feature
for applications with various loads.
„ Ultra low quiescent current of 15µA in typical.
„ Typical 2% internally trimmed output.
„ Output current is excess of 300mA.
„ Low Dropout Voltage.
„ P-MOS output stage with low R_DS(ON).
„ Short circuit protection.
„ Internal thermal overload protection.
„ Available in 3-Lead surface mount SOT-23
package.
