NCP690, NCP691, NCP692
1 A, Low IGND, Very Low
Dropout Regulator (VLDO)
with/without Enable
The NCP690, NCP691, NCP692 CMOS LDO family provides 1 A
of output current with enhanced ESD in either fixed voltage options or
an adjustable output voltage from 5.0 V down to 1.25 V. This device is
designed for space constrained and portable battery powered
applications and offer additional features such as high PSRR, low
Quiescent and Ground current consumption, low noise operation,
short circuit and thermal protection. The device is designed to be used
with low cost ceramic capacitors and is packaged in the 6−Lead
DFN3x3 package.
Features
• Output Voltage Options: Adjustable, 1.5 V, 1.8 V, 2.5 V, 3.3 V, 5.0 V
– Other Options Possible
• Adjustable Output by External Resistors from 5.0 V down to 1.25 V
• Guaranteed 1 A Output Current
• ±1.5% Output Voltage Tolerance over All Operating Conditions
(Adjustable)
• ±2% Output Voltage Tolerance over All Operating Conditions
(Fixed)
• Typical Noise Voltage of 50 mVrms without a Bypass Capacitor
• Typical Dropout Voltage of 190 mV at 1 A (Vout = 2.5 V, TJ = 25°C)
• Active Output Discharge
• Active Low Enable Pin (NCP691 Device)
• Active High Enable Pin (NCP692 device)
• Enhanced ESD: 4 kV and 400 V
Applications
• Laptops and PCI Cards
• Modem Banks and Telecom Boards
• DSP, FPGA, Microprocessor Boards
• Portable, Battery−Power Applications
