BL9180
Dual,300mA Ultra-low Noise
CMOS LDO Regulator
FEATURES
DESCRIPTION
Up to 300mA Output Current(Each LDO)
The BL9180 dual, low noise, low-dropout regulator
supplying up to 300mA output current at each
channel. The output voltage for each regulator is set
independently by trimming. Voltages are selectable
in 50mV steps within a range of 1.2V to 3.3V by
operating from a 2V to 6V input. The BL9180
includes two independent logic-controlled shutdown
inputs and allows the output of each regulator to be
turned off independently. When both outputs
shutdown simultaneously, the chip will be turn off
and consumes nearly zero operation current which
is suitable for battery-power devices.
Dual Shutdown Pins Control Each Output
90uA Operating supply current per LDO
Excellent Line regulation:0.05%/V
Low Dropout:220mV@300mA
High Power Supply Rejection Ratio

High Accuracy: ±1% or ±2%
Internal Pulled down(8 MΩ)resistor
Current Limiting and Thermal Protection
Two LDOs in SOT-23-6 and ESOP-8 Package
RoHS Compliant and 100% Lead(Pb)-Free
The BL9180 includes high accuracy voltage
reference, error amplifier, current limit circuit and
output driver module.
APPLICATIONS

Applications Information
protection.
The BL9180 is integrated with two low
noise, low dropout and low quiescent
current linear regulators designed primarily
for battery applications. Output voltages
are optional ranging from 1.2V to 3.3V, and
each channel can supply current up to 300
mA.
Operating Region and Power
Dissipation
The maximum power dissipation of BL9180
depends on the thermal resistance of the
case and circuit board, the temperature
difference between the die junction and
ambient air, and the rate of airflow. The
power dissipation across the device is
Enable Function
The BL9180 is shutdown by pulling the EN
input low, and turn on by driving the input
high. If this feature is not be used, the EN
input should be tied to VIN to keep the
regulator on at all times.
PD = (VIN−VOUT) ×IOUT + VIN×I Q
The maximum power dissipation is:
PD(MAX) = ( TJ(MAX) − TA ) /θJA
Current Limit and Thermal Protection
Where TJ(MAX) is the maximum operation
junction temperature 125°C, TA is the
ambient temperature and the θJA is the
junction to ambient thermal resistance. The
GND pin of the BL9180 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.
The BL9180 includes two independent
current limit structure which monitor and
control each pass transistor’s gate voltage
limiting the guaranteed maximum output
current to 300mA. Thermal overload
protection limits total power dissipation in
the
BL9180.

protection is designed to protect the

continuous operation. The output can be
shorted to ground for an indefinite amount
of time without damaging the part by

Like any low-dropout regulator, the external
capacitors used with the BL9180 must be
carefully selected for regulator stability and
performance. The BL9180 requires an
output capacitor between the VOUT and
GND pins for phase compensation. Using a
capacitor whose value is > 1μF on the
BL9180 input and the amount of

capacitance can be increased without limit.
The input capacitor must be located a
distance of not more than 0.5 inch from the
input pin of the IC and returned to a clean
analog ground. Any good quality ceramic or
tantalum can be used for this capacitor.
The capacitor with larger value and lower
impedance due to the load current change,
and the transient response. The DC shift is
quite small due to the excellent load
regulation of the IC. Typical output voltage
transient spike for a step change in the load
current from 0mA to 50mA is tens of mV,
depending on the ESR of the output
capacitor. Increasing the output capacitor's
value and decreasing the ESR attenuates
the overshoot.
ESR

series
resistance)
provides better PSRR and line-transient
response. The output capacitor must meet
both requirements for minimum amount of
capacitance and ESR in all LDOs
applications. The BL9180 is designed
specifically to work with low ESR ceramic
output capacitor in space-saving and

works well with output capacitor of other
types due to the wide stable ESR range.
Output capacitor of larger capacitance can

Layout Considerations
To improve ac performance such as PSRR,
output noise, and transient response, it is
recommended that the PCB be designed
with separate ground planes for VIN and
VOUT, with each ground plane connected
only at the GND pin of the device.
Load-Transient Considerations
