January 2020
Rev. 2.1.1
GENERAL DESCRIPTION
APPLICATIONS
The SP6200 and SP6201 are CMOS Low
Dropout (LDO) regulators designed to meet a
broad range of applications that require
accuracy, speed and ease of use.
• Battery-Powered Systems
These LDOs offer extremely low quiescent
current which only increases slightly under
load, thus providing advantages in ground
current performance over bipolar LDOs. The
LDOs handle an extremely wide load range
and guarantee stability with a 1μF ceramic
output capacitor. They have excellent low
frequency Power Supply Rejection Ratio
(PSRR), not found in other CMOS LDOs and
thus offer exceptional Line Regulation. High
frequency PSRR is better than 40dB up to
400kHz. Load Regulation is excellent and
temperature stability is comparable to bipolar
LDOs. An enable feature is provided on all
versions.

OPERATING RATINGS
These are stress ratings only and functional operation of
the device at these ratings or any other above those
indicated in the operation sections of the specifications
below is not implied. Exposure to absolute maximum
rating conditions for extended periods of time may affect
reliability.
Input Voltage Range VIN ............................. +2.5V to +6V
Enable Input Voltage (VEN) ................................ 0V to 6V
Junction Temperature Range ....................-40°C to 125°C
Thermal Resistance ......................................................
SOT-23-5 (θJA) .............................................191°C/W
DFN-8 (θJA) ................................................... 59°C/W
Supply Input Voltage (VIN) ............................... -2V to 7V
Output Voltage (VOUT)............................ -0.6 to (VIN +1V)
Enable Input Voltage (VEN) ............................... -2V to 7V
Storage Temperature ............................ -65°C to +150°C
Power Dissipation ............................... Internally Limited1
Lead Temperature (Soldering, 5 sec) ..................... 260°C
Note 1: Maximum power dissipation can be calculated
using the formula: PD = (TJ(max) - TA) / θJA, where
TJ(max) is the junction temperature, TA is the ambient
temperature and θJA is the junction-to-ambient thermal
resistance. θJC is 6°C/W for this package. Exceeding the
maximum allowable power dissipation will result in
excessive die temperature and the regulator will go into
thermal shutdown mode.
ELECTRICAL SPECIFICATIONS
Specifications with standard type are for an Operating Junction Temperature of TJ = 25°C only; limits applying over the full
Operating Junction Temperature range are denoted by a “•”. Minimum and Maximum limits are guaranteed through test,
design, or statistical correlation. Typical values represent the most likely parametric norm at TJ = 25°C, and are provided for
reference purposes only. Unless otherwise indicated, VIN = (VOUT + 1V), VOUT = 5V for Adjustable version, CIN = 1.0µF, COUT =
1.0µF and IL = 100µA, TJ= 25°C.

Note 2: Output voltage temperature coefficient is defined as the worst case voltage change divided by the totaltemperature
range.
Note 3: Load Regulation is measured at constant junction temperature using low duty cycle pulse testing. Parts are tested
for load regulation in the load range; from 0.1mA to 100mA, SP6200; from 0.1mA to 200mA, SP6201. Changes in output
voltage due to heating effects are covered by the thermal regulation specification. Not applicable to output voltages less
than 2.5V.
Note 4: Dropout Voltage is defined as the input to output differential at which the output voltage drops 2% below its
nominal value measured at 1V differential. Not applicable to output voltages less than 2.7V.
Note 5: Ground pin current is the regulator quiescent current. The total current drawn from the supply is the sum of the
load current plus the ground pin current.
Note 6: Thermal regulation is defined as the change in output voltage at a time ”t” after a change in power dissipation is
applied, excluding load or line regulation effects. Specifications are for a 100mA load pulse at VIN = 6V for t = 10ms.

THEORY OF OPERATION
LDOs have a two stage amplifier which
handles an extremely wide load range (10μA
to 300mA) and guarantees stability with a 1μF
ceramic load capacitor. The LDO amplifier has
excellent
gain
and
thus
touts
PSRR
performance not found in other CMOS LDOs.
The amplifier guarantees no overshoot on
power up or while enabled through the EN pin.
The amplifier also contains an active pull
down, so that when the load is removed
quickly the output voltage transient is
minimal; thus output deviation due to load
transient is small and fairly well matched when
connecting and disconnecting the load.
GENERAL OVERVIEW
The SP6200 and SP6201 are CMOS LDOs
designed to meet a broad range of
applications that require accuracy, speed and
ease of use. These LDOs offer extremely low
quiescent current which only increases slightly
under load, thus providing advantages in
ground current performance over bipolar
LDOs. The LDOs handle an extremely wide
load range and guarantee stability with a 1μF
ceramic output capacitor. They have excellent
low frequency PSRR, not found in other CMOS
LDOs and thus offer exceptional Line
Regulation. High frequency PSRR is better
than 40dB up to 400kHz. Load Regulation is
excellent
and
temperature
stability
is
comparable to bipolar LDOs. Thus, overall
system accuracy is maintained under all DC
and AC conditions. Enable feature is provided
on all versions. A Vout good indicator (RSN
pin) is provided in all the fixed output voltage
devices. An adjustable output version is also
available.
Current
Limit
and
Thermal
protection is provided internally and is well
controlled.
An accurate 1.250V bandgap reference is
bootstrapped to the output in fixed output
versions of 2.7V and higher. This increases
both the low frequency and high frequency
PSRR. The adjustable version also has the
bandgap reference bootstrapped to the output,
thus the lowest externally programmable
output voltage is 2.7V. The 2.5V fixed output
version has the bandgap always connected to
the Vin pin. Unlike many LDOs, the bandgap
reference is not brought out for filtering by the
user. This tradeoff was made to maintain good
PSRR at high frequency (PSRR can be
degraded in a system due to switching noise
coupling into this pin). Also, often leakages of
the bypass capacitor or other components
cause an error on this high impedance
bandgap node. Thus, this tradeoff has been
made with "ease of use" in mind.
ARCHITECTURE
The SP6200 and SP6201 are only different in
their current limit threshold. The SP6200 has a
current limit of 140mA, while the SP6201
current limit is 420mA. The SP6201 can
provide pulsed load current of 300mA. The

bootstrapped to the output, the output voltage
must be above the minimum bandgap supply
voltage. The bandgap requires 2.7V or greater
at -40°C and requires 2.5V or greater at 0°C.
The regulator's output can be adjusted to a
specific output voltage by using two external
resistors, see block diagram. The resistor's set
the output voltage based on the following
equation:
Current limit behavior is very well controlled,
providing less than 10% variation in the
current limit threshold over the entire
temperature range for both SP6200 and
SP6201. The SP6200 has a current limit of
140mA, while the SP6201 has a current limit
of 420mA. Thermal shutdown activates at
162°C and deactivates at 147°C. Thermal
shutdown is very repeatable with only a 2 to 3
degree variation from device to device.
Thermal shutdown changes by only 1 to 2
degrees with Vin change from 4V to 7V.

Resistor values are not critical because the
ADJ node has a high input impedance, but for
best results use resistors of 470kΩ or less. A
capacitor from ADJ to VOUT pin provides
improved noise performance as is shown in
the following plot.
ENABLE (SHUTDOWN NOT) INPUT
The LDOs are turned off by pulling the EN pin
low and turned on by pulling it high. If it is not
necessary to shut down the LDO, the EN (pin
3) should be tied to IN (pin 1) to keep the
regulator output on at all time. The enable
threshold is 0.9V and does not change more
than 100mV over the entire temperature and
VIN voltage range. The lot to lot variations in
Enable Threshold are also within 100mV.
Shutdown current is guaranteed to be
