Title:
LOW-TEMPERATURE-DRIFT LINEAR VOLTAGE STABILIZER WITH EXTREMELY LOW POWER CONSUMPTION
Document Type and Number:
WIPO Patent Application WO/2020/233382
Kind Code:
A1
Abstract:
A low-temperature-drift linear voltage stabilizer with extremely low power consumption. By use of the voltage stabilizer, the closed-loop control of a conventional linear voltage stabilizer is blended into a reference voltage generation circuit. The voltage stabilizer comprises: nine PMOS tubes, which are respectively a PMOS tube PM1 to a PMOS tube PM9; two resistors, which are respectively a resistor R1 and a resistor R2; two capacitors, which are respectively a capacitor C1 and a capacitor C2; and two NMOS tubes, which are respectively an NMOS tube NM1 and an NMOS tube NM2. A linear voltage stabilization function of the low temperature drift under the extremely low power consumption can be implemented by fewest circuit branches and a minimum transistor number. The voltage stabilizer has the characteristics of simple structure, low static power consumption, and large output driving range.
