0 V/2.
0 A REGULATOR 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 PIN CONFIGURATION (Marking Side) 5-PIN TO-252 (5-PIN MP-3ZK) 6 1.
