BIPOLAR ANALOG INTEGRATED CIRCUIT
μ PC29xxB Series
THREE-TERMINAL LOW DROPOUT VOLTAGE REGULATOR
(OUTPUT CURRENT: 1.0 A)
DESCRIPTION
The μ PC29xxB series is a series of three-terminal low dropout voltage regulators with 1.0 A output current. This
series is suitable for low voltage operated IC and has 4 output voltage types, 1.8 V, 2.5 V, 3.3 V and 5.0 V. Compared
with the μ PC29xx and μ PC29xxA series, this series has improved output voltage tolerance (VO ± 2%), quiescent
current (1.8 mA TYP. (IO = 0 A)), and short-circuit current.
FEATURES
• Output current capacity: 1.0 A
• Output voltage tolerance: VO ± 2% (TA = 25°C)
• Low quiescent current: 1.8 mA TYP. (IO = 0 A)
• Low short-circuit current: 0.3 A TYP. (μ PC2918B), 0.6 A TYP. (μ PC2925B, μ PC2933B), 0.65 A TYP. (μ PC2905B)
• Low dropout voltage: VDIF = 0.6 V MAX. (IO = 0.5 A)
• On-chip inrush current protection circuit at the time of input voltage rising (when input voltage is low)
• On-chip over-current limiter
• On-chip thermal shut down circuit
APPLICATIONS
Digital TV, DVD, LCD Monitors, Printers, Audio, Air Conditioners, and other applications.
