µPC2400A Series
THREE TERMINAL LOW DROPOUT VOLTAGE REGULATOR
DESCRIPTION
µPC2400A Series are low dropout regulators which have 1 A capable for the output current.
These ICs are built-in the saturation protection circuit of the output transistor.
FEATURES
• Built-in the saturation protection circuit of the output transistor. • The capability of output current is 1 A • High accuracy of output voltage. | ∆ VO | ≤ ±2 % (TJ = 25 ˚C) | ∆ VO | ≤ ±3 % (0 ˚C ≤ TJ ≤ 125 ˚C) • Low dropout voltage. VDIF ≤ 1 V (IO ≤ 1 A, TJ ≤ 125 ˚C) • Built-in overcurrent protection circuit, thermal shut-down circuit. • Built-in Safe Operating Area protection circuit. • Compatible for µPC2400 Series.
