HIP6211
Dual Low Noise LDO in 3mm×3mm MLFTM
Description
The HIP6211 is a dual CMOS low dropout linear
regulator with ultra-low-noise output, very low
dropout voltage and very low ground current.
The HIP6211 operates from a 2.5V to 5.5V input
voltage range and delivers up to 300mA, with low
dropout of 150 mV at 300mA. The other features of
HIP6211 include short-circuit protection and
thermal-shutdown protection.
Its dual channel and low noise feature is ideal for
microcontroller
and
DSP
based
handheld
applications.
Other key application areas for HIP6211 also
include palmtop computers, PCMCIA cards and
WLAN cards.
The HIP6211 has a special feature that if both EN
pin is enabled simultaneously the output of LDO2
delays 20us from output of LDO1 which helps to
minimize inrush startup current.
The HIP6211 is available in tiny 10pin 3mm x 3mm
MLF (10L-TDLMF) package with fixed output
voltage versions.

HIP6211
Dual Low Noise LDO in 3mm×3mm MLFTM
Operation Description
The HIP6211 are ultra-low-noise, low-dropout, lowquiescent current linear regulators designed for
space-restricted applications. These devices can
supply loads up to 300mA. As shown in the Block
Diagram, the HIP6211 consists of a highly accurate
band gap core, noise bypass circuit, error amplifier,
P-channel pass transistor and an internal feedback
voltage divider. The 1.0V band gap reference is
connected to the error amplifier’s inverting input.
The error amplifier compares this reference with
the feedback voltage and amplifies the difference.
If the feedback voltage is lower than the reference
voltage, the pass transistor gate is pulled low. This
allows more current to pass to the output and
increases the output voltage. If the feedback
voltage is too high, the pass transistor gate is
pulled high, allowing less current to pass to the
output. The output voltage is feedback through an
internal resistor voltage divider connected to the
OUT pin. An external bypass capacitor connected
to BYP reduces noise at the output. Additional
blocks include a current limiter, over temperature
protection, and shutdown logic.
Internal P-Channel Pass Transistor
The HIP6211 feature a 1Ω (typ) P-channel MOSFET
pass transistor. This provides several advantages
over similar designs using a PNP pass transistor,
including longer battery life. The P-channel MOSFET
requires no base drive, which considerably reduces
quiescent current. PNP-based regulators waste
considerable current in dropout when the pass
transistor saturates. They also use high base-drive
current under heavy loads. The HIP6211 does not
suffer from these problems and consume only
200µA of quiescent current in light load.
Current Limit
The HIP6211 includes a current limiter. It monitors
the output current and controls the pass transistor’s
gate voltage to limit the output current under
600mA (typ). The output can be shorted to ground
for an indefinite amount of time without damaging
the part.
Enable Input
The HIP6211 features an active-high Enable input
(EN) pin that allows on/off control of the regulator.
The HIP6211 bias current reduces to less than
microampere of leakage current when it is
shutdown. The Enable input is TTL/CMOS
compatible threshold for simple logic interfacing.
When EN is ‘H,’ the output voltage startup rising
time is 35us typically at 300mA output current.
Connect EN pin to IN pin for normal operation
Under Voltage Lockout
When the input supply goes too low (below 2.0V)
the HIP6211 produces an internal UVLO (under
voltage lockout) signal that generates a fault signal
and shuts down the chip. This mechanism protects
the chip from producing false logic due to low input
supply.
Quick Charging Mode
The HIP6211 has a quick charge block to get the
reference up very quickly by charging the BYP
capacitor with very high current when the chip
comes out of shut down. This quick charge block
stops charging the BYP capacitor when the
reference reaches 95% of its nominal value and
then the chip switches out of quick charging mode
to normal operating mode.
Over Temperature Protection
Over temperature protection limits total power
dissipation in the HIP6211. When the junction
temperature exceeds Tj= +165°C, the thermal
sensor signals the shutdown logic and turns off the
pass transistor. The thermal sensor turns the pass
transistor on again after the IC’s junction
temperature drops by 20°C, resulting in a pulsed
output
during
continuous
thermal-overload
conditions.
Thermal-Overload protection is design to protect
the HIP6211 in the event of a fault condition. For
continual operation, do not exceed the absolute
maximum junction temperature rating of Tj =
+150°C.

Dual Low Noise LDO in 3mm×3mm MLFTM
Operating Region and Power Dissipation
The HIP6211 maximum power dissipation depends
on 1) the thermal resistance of the case and circuit
board, 2) the temperature difference between the
die junction and ambient, and 3) the rate of airflow.
The power dissipation across the device is:
P = Iout ( Vin – Vout )
The maximum power dissipation is:
temperatures below -10°C. With X7R or X5R
dielectrics, 1µF is sufficient at all operating
temperatures. A graph of the region of stable Cout
ESR vs. load current is shown in the Typical
Characteristics.
Pmax = (Tj – Ta) / (θjc + θca)
Where (Tj – Ta) is the temperature difference
between the HIP6211 die junction and the ambient
air; θjc is the thermal resistance of the package;
and θca is the thermal resistance through the PC
board, copper traces, and other materials to the
surrounding air.
The GND pin of the HIP6211 performs the dual
function of providing an electrical connection to
ground and channeling heat away. Connect the
GND pin to ground using a large pad or ground
plane.
Noise Reduction
For the HIP6211, an external 0.01µF bypass
capacitor between BYP and GND with innovative
noise bypass scheme reduces output noises
dramatically, exhibiting 100µVrms of output voltage
noise with Cbyp = 0.01µF and Cout = 1µF.
Application Information
Capacitor Selection and Regulator Stability
Use a 1µF capacitor on the HIP6211 input and a
1µF capacitor on the output. Large input capacitor
values and lower ESRs provide better noise
rejection and line-transient response.
Reduce output noise and improve load-transient
response, stability, and power-supply rejection by
using large output capacitors. Note that some
ceramic dielectrics exhibit large capacitance and
ESR variation with temperature. With dielectrics
such as Z5U and Y5V, it may be necessary to use a
1µF or larger output capacitor to ensure stability at
Use a 0.01µF bypass capacitor at BYP for lowoutput voltage noise. The leakage current going
into the BYP pin should be less than 10nA.
Noise, PSRR, and Transient Response
The HIP6211 are designed to deliver ultra-low noise
and high PSRR, as well as low dropout and low
quiescent currents in battery-powered systems. The
HIP6211 PSRR is 75dB at 100Hz and 70dB at 10kHz
(see the Power-Supply Rejection Ratio vs.
Frequency graph in the Typical Characteristic).
When operating from sources other than batteries,
improved supply-noise rejection and transient
response can be achieved by increasing the values
of the input and output bypass capacitors, and
through passive filtering techniques. The Typical
Characteristics show the HIP6211 line and load
transient responses.
Dropout Voltage
A regulator’s minimum dropout voltage determines
the lowest usable supply voltage. In batterypowered systems, this determines the useful endof-life battery voltage. Because the HIP6211 use a
P-channel MOSFET pass transistor, their dropout
voltage is a function of drain-to-source on
resistance (RDS (on)) multiplied by the load current
(see the Typical Characteristics).
