MC78PC00/D
MC78PC00 Series
Low Noise 150 mA
Low Drop Out (LDO)
Linear Voltage Regulator
The MC78PC00 are a series of CMOS linear voltage regulators with
high output voltage accuracy, low supply current, low dropout voltage,
and high Ripple Rejection. Each of these voltage regulators consists of
an internal voltage reference, an error amplifier, resistors, a current
limiting circuit and a chip enable circuit.
The dynamic Response to line and load is fast, which makes these
products ideally suited for use in hand−held communication
equipment. The MC78PC00 series are housed in the SOT−23 5 lead
package, for maximum board space saving.
MC78PC00 Features:
• Ultra−Low Supply Current: typical 35 mA in ON mode with no load.
• Standby Mode: typical 0.1 mA.
• Low Dropout Voltage: typical 0.2 V @ I
OUT
= 100 mA.
• High Ripple Rejection: typical 70 dB @ f = 1 kHz.
• Low Temperature−Drift Coefficient of Output Voltage:
typical ±100 ppm/°C.
• Excellent Line Regulation: typical 0.05%/V.
• High Accuracy Output Voltage: ±2.0%.
• Fast Dynamic Response to Line and Load.
• Small Package: SOT−23 5 leads.
• Built−in Chip Enable circuit (CE input pin).
• Identical Pinout to the LP2980/1/2.
• Pb−Free Packages are Available
MC78PC00 Applications:
• Power source for cellular phones (GSM, CDMA, TDMA), Cordless
Phones (PHS, DECT) and 2−way radios.
• Power source for domestic appliances such as cameras, VCRs and
camcorders.
• Power source for battery−powered equipment.

Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit
values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied,
damage may occur and reliability may be affected.

ERROR AMP.
In the MC78PC00, the output voltage V

is detected by R1, R2. The detected output voltage is then compared to the
internal voltage reference by the error amplifier. Both a current limiting circuit for short circuit protection, and a chip enable
circuit are included.
