SC1565
Very Low Dropout
1.5 Amp Regulator With Enable
POWER MANAGEMENT
Description
Features
The SC1565 is a high performance positive voltage
regulator designed for use in applications requiring very
low dropout voltage at up to 1.5 Amps. Since it has
superior dropout characteristics compared to regular
LDOs, it can be used to supply 2.5V on motherboards or
2.8V on peripheral cards from the 3.3V supply thus
allowing the elimination of costly heatsinks. Additionally,
the 5-lead TO-220/TO-263 and SO-8 versions have an
enable pin to further reduce power dissipation while shut
down. The SC1565 provides excellent regulation over
variations in line, load and temperature.
‹ 350mV dropout @ 1.5A
‹ Adjustable output from 1.2V to 4.8V(1)
‹ 2.5V and 1.8V options (adjustable externally
using resistors)(1)
‹ Over current and over temperature protection
‹ Enable pin(1)
‹ 10µA quiescent current in shutdown(1)
‹ Low reverse leakage (output to input)
‹ Surface mount and through-hole packages
‹ Full industrial temperature range
‹ TO-220, TO-263, SOT-223 and SO-8 Packages
Note:
(1) SO-8, TO-220-5 and TO-263-5 packages only.
The SC1565 is available in SO-8, 3-lead SOT-223, 3 and
5 lead TO-220 and 3 and 5 lead TO-263 packages. Three
lead packages are available with 1.8V and 2.5V fixed
output options only. The SO-8, TO-220-5 and TO-263-5
are available with 1.8V and 2.5V internally preset
outputs that are also adjustable using external resistors.

(2) Defined as the input to output differential at which the output voltage drops to 1% below the value
measured at a differential of 0.7V.
(3) Required to maintain regulation. Voltage set resistors R1 and R2 are usually utilized to meet this
requirement. Adjustable versions only.
(4) Guaranteed by design.
(5) When VADJ exceeds this threshold, the “Sense Select” switch disconnects the internal feedback chain from
the error amplifier and connects VADJ instead.

Applications Information
Introduction
Thermal Considerations
The SC1565 is intended for applications such as
graphics cards where high current capability and very low
dropout voltage are required. It provides a very simple,
low cost solution that uses very little pcb real estate.
Additional features include an enable pin to allow for a
very low power consumption standby mode, and a fully
adjustable output.
The power dissipation in the SC1565 is approximately
equal to the product of the output current and the input
to output voltage differential:
Component Selection
PD ( MAX ) = (VIN
PD ≈ (VIN − VOUT ) • I O
The absolute worst-case dissipation is given by:
( MAX )
− VOUT
( MIN )
)• I
O ( MAX )
+ VIN
( MAX )
• I Q ( MAX )
Input capacitor: a 4.7µF ceramic capacitor is
recommended. This allows for the device being some
distance from any bulk capacitance on the rail.
Additionally, input droop due to load transients is reduced,
improving load transient response. Additional capacitance
may be added if required by the application.
For a typical scenario, VIN = 3.3V ± 5%, VOUT = 2.8V and
IO = 1.5A, therefore:
Output capacitor: a minimum bulk capacitance of 2.2µF,
along with a 0.1µF ceramic decoupling capacitor is
recommended. Increasing the bulk capacitance will
improve the overall transient response. The use of
multiple lower value ceramic capacitors in parallel to
achieve the desired bulk capacitance will not cause
stability issues. Although designed for use with ceramic
output capacitors, the SC1565 is extremely tolerant of
output capacitor ESR values and thus will also work
comfortably with tantalum output capacitors. For reference, the phase-margin contour of Figure 1 can be used
to choose an appropriate output capacitor for a given
stability requirement.
Using this figure, and assuming TA(MAX) = 70°C, we can
calculate the maximum thermal impedance allowable to
maintain TJ ≤ 150°C:
VIN(MAX) = 3.465V, VOUT(MIN) = 2.744V and IQ(MAX) = 1.75mA,
Thus PD(MAX) = 1.09W.
R TH( J − A )(MAX ) =
(T
J( MAX )
− TA (MAX )
PD ( MAX )
) = (150 − 70 ) = 73.4° C / W
.
109
This should be achievable for the SO-8 package using
pcb copper area to aid in conducting the heat away, such
as one square inch of copper connected to the ground
pins of the device. The SOT-223, TO-220 and TO-263
packages would not require heatsinking. Internal ground/
power planes and air flow will also assist in removing
heat. For higher ambient temperatures it may be necessary to use additional copper area.
Noise immunity: in very electrically noisy environments,
it is recommended that 0.1µF ceramic capacitors be
placed from IN to GND and OUT to GND as close to the
device pins as possible.
External voltage selection resistors: the use of 1%
resistors, and designing for a current flow ≥ 10µA is
recommended to ensure a well regulated output (thus
R2 ≤ 120kΩ).
