LDO with Low ISUPPLY, High PSRR
ISL9001 is a high performance Low Dropout linear regulator
capable of sourcing 300mA current. It has a low standby
current and high-PSRR and is stable with an output
capacitance of 1µF to 10µF with an ESR of up to 200m.
Features
The ISL9001 has a very high PSRR of 90dB and outputs
noise less than 30µVRMS. A reference bypass pin allows
connection of a noise-filtering capacitor for low-noise and
high-PSRR applications. When coupled with a no load
quiescent current of 25µA (typical), and 0.1µA shutdown
current, the ISL9001 is an ideal choice for portable wireless
equipment.
• Excellent load regulation: <0.1% voltage change across
full range of load current
• 300mA high performance LDO
• Excellent transient response to large current steps
• High PSRR: 90dB @ 1kHz
• Wide input voltage capability: 2.3V to 6.5V
• Extremely low quiescent current: 25µA
• Low dropout voltage: typically 200mV @ 300mA
The ISL9001 provides a power-good signal with delay time
programmable with an external capacitor.
• Low output noise: typically 30µVRMS @ 100µA (1.5V)
Several different fixed voltage outputs are standard. Output
voltage options for each LDO range are from 1.5V to 3.3V.
Other output voltage options may be available upon request.
• Soft-start to limit input current surge during enable
• Stable with 1µF to 10µF ceramic capacitors
• Current limit and overheat protection
• Delayed POR, programmable with external capacitor
Pinout
• ±1.8% accuracy over all operating conditions

Functional Description
The ISL9001 contains all circuitry required to implement a
high performance LDO. High performance is achieved
through a circuit that delivers fast transient response to
varying load conditions. In a quiescent condition, the
ISL9001 adjusts its biasing to achieve the lowest standby
current consumption.
The device also integrates current limit protection, smart
thermal shutdown protection, and soft-start. Smart Thermal
shutdown protects the device against overheating.
Power Control
The ISL9001 has an enable pin (EN) to control power to the
LDO output. When EN is low, the device is in shutdown
mode. During this condition, all on-chip circuits are off, and
the device draws minimum current, typically less than 0.1µA.
When the enable pin is asserted, the device first polls the
output of the UVLO detector to ensure that VIN voltage is at
least about 2.1V. Once verified, the device initiates a start-up
sequence. During the start-up sequence, trim settings are
first read and latched. Then, sequentially, the bandgap,
reference voltage and current generation circuitry power-up.
Once the references are stable, a fast-start circuit quickly
charges the external reference bypass capacitor (connected
to the CBYP pin) to the proper operating voltage. Once the
bypass capacitor has been charged, the LDO powers up.

During operation, whenever the VIN voltage drops below
about 1.84V, the ISL9001 immediately disables the LDO
output. When VIN rises back above 2.1V, the device
re-initiates its start-up sequence and LDO operation will
resume automatically.
Reference Generation
The reference generation circuitry includes a trimmed
bandgap, a trimmed voltage reference divider, a trimmed
current reference generator, and an RC noise filter. The filter
includes the external capacitor connected to the CBYP pin.
A 0.01µF capacitor connected to CBYP implements a 100Hz
lowpass filter, and is recommended for most high
performance applications. For the lowest noise application, a
0.1µF CBYP capacitor should be used. This filters the
reference noise to below the 10Hz to 1kHz frequency band,
which is crucial in many noise-sensitive applications.
The bandgap generates a zero temperature coefficient (TC)
voltage for the reference divider. The reference divider
provides the regulation reference, POR detection thresholds,
and other voltage references required for current generation
and over-temperature detection.
The current generator outputs references required for
adaptive biasing as well as references for LDO output
current limit and thermal shutdown determination.

ISL9001
LDO Regulation and Programmable Output Divider
The LDO Regulator is implemented with a high-gain
operational amplifier driving a PMOS pass transistor. The
design of the ISL9001 provides a regulator that has low
quiescent current, fast transient response, and overall stability
across all operating and load current conditions. LDO stability
is guaranteed for a 1µF to 10µF output capacitor that has a
tolerance better than 20% and ESR less than 200m. The
design is performance-optimized for a 1µF capacitor. Unless
limited by the application, use of an output capacitor value
above 4.7µF is not recommended as LDO performance
improvement is minimal.
Soft-start circuitry integrated into each LDO limits the initial
ramp-up rate to about 30µs/V to minimize current surge. The
ISL9001 provides short-circuit protection by limiting the output
current to about 425mA.
The LDO uses an independently trimmed 1V reference as its
input. An internal resistor divider drops the LDO output voltage
down to 1V. This is compared to the 1V reference for
regulation. The resistor division ratio is programmed in the
factory.
Power-On Reset Generation
The power-good state is exited when the LDO output falls
below 90% of the expected output voltage for a period longer
than the PGOOD exit delay time. While power-good is false,
the ISL9001 pulls the POR pin low.
The PGOOD entry and exit delays are determined by the value
of an external capacitor connected to the CPOR pin. For a
0.01µF capacitor, the entry and exit delays are 200ms and
25µs respectively. Larger or smaller capacitor values will yield
proportionately longer or shorter delay times. The POR exit
delay should never be allowed to be less than 10µs to ensure
sufficient immunity against transient induced false POR
triggering.
Overheat Detection
The bandgap outputs a proportional-to-temperature current
that is indicative of the temperature of the silicon. This current
is compared with references to determine if the device is in
danger of damage due to overheating. When the die
temperature reaches about +140°C, if the LDO is sourcing
more than 50mA it shuts down until the die cools sufficiently.
Once the die temperature falls back below about +110°C, the
disabled LDO is re-enabled and soft-start automatically takes
place.
The ISL9001 has a Power-on Reset signal generation circuit,
which indicates that output power is good. The POR signal is
generated as follows.
A POR comparator continuously monitors the output of the
LDO. The LDO enters a power-good state when the output
voltage is above 94% of the expected output voltage for a
period exceeding the LDO PGOOD entry delay time (see the
following). In the power-good state, the open-drain POR output
is in a high-impedance state. An internal 100k pull-up resistor
pulls the pin up to the LDO output voltage. An external resistor
can be added between the POR output and the LDO output for
a faster rise time, however, the POR output should not connect
through an external resistor to a supply greater than the LDO
voltage.
