MOS INTEGRATED CIRCUIT
μ PD121A10
2-POWER SUPPLY INPUT METHOD
1.0 V/2.0 A REGULATOR
DATA SHEET

Printed in Japan
DESCRIPTION
μ PD121A10 is the CMOS regulator which can output 2.0 A current. This regulator is suitable for power supply for 1.0
V ASIC core, for example our companies’ CB-90 (90 nm process LSI) etc. The dropout voltage is made small (0.7 V
MAX. (IO = 1.0 A) by dividing bias voltage (VDD) from input voltage (VIN). Therefore this product can output under the
conditions, VIN
≥ 1.62 V (VDD ≥ 4.0 V). Output voltage can be adjustable between 0.95 and 1.15 V.
FEATURES
Output Current: 2.0 A
Output Voltage: 0.95 to 1.15 V
Bias Voltage: 4.0 to 5.5 V
Reference Voltage Tolerance: VREF ± 10 mV (TJ = 25°C)
Low Dropout Voltage: VDIF = 0.7 V MAX. (IO = 1.0 A)
On-chip over-current protection circuit
On-chip thermal shut down circuit
APPLICATIONS
This regulator is suitable for low power supply voltage IC,
for example core of CB-90 (90 nm process LSI) etc.
