Ultra Low Dropout 1A, 2A, 3A Low Input Voltage NMOS
LDOs
ISL80111, ISL80112, ISL80113
The ISL80111, ISL80112, and ISL80113 are ultra low dropout
LDOs providing the optimum balance between performance, size
and power consumption in size constrained designs for data
communication, computing, storage and medical applications.
These LDOs are specified for 1A, 2A and 3A of output current and
are optimized for low voltage conversions. Operating with a VIN of
1V to 3.6V and with a legacy 2.9V to 5.5V on the BIAS, the VOUT is
adjustable from 0.8V to 3.3V. With a VIN PSRR greater than 40dB
at 100kHz makes these LDOs an ideal choice in noise sensitive
applications. The guaranteed ±1.6% VOUT accuracy overall
conditions lend these parts to supplying an accurate voltage to
the latest low voltage digital ICs.
An enable input allows the part to be placed into a low quiescent
current shutdown mode. A submicron CMOS process is utilized for
this product family to deliver best-in-class analog performance
and overall value for applications in need of input voltage
conversions typically below 2.5V. It also has the superior load
transient regulation unique to a NMOS power stage. These LDOs
consume significantly lower quiescent current as a function of
load compared to bipolar LDOs.
Features
• Ultra low dropout: 75mV at 3A, (typical)
• Excellent VIN PSRR: 70dB at 1kHz (typical)
• ±1.6% guaranteed VOUT accuracy for -40ºC < TJ < +125ºC
• Very fast load transient response
• Extensive protection and reporting features
• VIN range: 1V to 3.6V, VOUT range: 0.8V to 3.3V
• Small 10 Ld 3x3 DFN package
Applications
• Noise-sensitive instrumentation and medical systems
• Data acquisition and data communication systems
• Storage, telecommunications and server equipment
• Low voltage DSP, FPGA and ASIC core power supplies
• Post-regulation of switched mode power supplies
