EUP7201

Dual ,Low-Noise,150mA LDO Regulator

DESCRIPTION

The EUP7201 is highly accurate, Dual, low noise, CMOS
LDO voltage regulator. Performance features include low
output noise, high ripple rejection ratio, low dropout and
very fast turn-on times.

The EUP7201 is also fully compatible with low ESR
ceramic capacitors, reducing cost and improving output
stability. This high level of output stability is maintained
even during frequent load fluctuations, due to the excellent
transient response performance and high PSRR achieved
across a broad range of frequencies.

The EN function allows the output of each regulator to be
turned off independently, resulting in greatly reduced
power consumption. The EUP7201 is available in the
SOT23-6 , TDFN-6 and USP-6 package.

Application Note

External Capacitors

Capacitor Characteristics

Like any low-dropout regulator, the EUP7201 requires
external capacitors for

regulator stability. The EUP7201 is

specifically designed for portable applications requiring
minimum board space and smallest components. These
capacitors must be correctly selected for good
performance.

Input Capacitor

An input capacitance of

1µF is required between the

≈

EUP7201 input pin and ground (the amount of the
capacitance may be increased without limit).
This capacitor must be located a distance of not more than
1cm from the input pin and returned to a clean analog
ground. Any good quality ceramic, tantalum, or film
capacitor may be used at the input.

If a tantalum capacitor is used at the input, it must be
guaranteed by the manufacturer to have a

surge current

rating sufficient for the application.
There are no requirements for the ESR on the input
capacitor, but tolerance and temperature coefficient must
be considered when selecting the capacitor to
capacitance will be

1µF over the entire operating

≈

ensure the

temperature range.

Output Capacitor

The EUP7201 is designed specifically to work with very
small ceramic output capacitors. A ceramic capacitor
(temperature characteristics X7R, X5R, Z5U, or Y5V) in 1
to 22µF range with 5mΩ to

500mΩ ESR range is suitable

in the EUP7201 application circuit.
The output capacitor must meet the requirement for
minimum amount of capacitance and also have an ESR
(Equivalent Series Resistance) value which is within a
stable range (5mΩ to 500mΩ)

No-Load Stability

The EUP7201 will remain stable and in regulation with no
external load. This is specially important in CMOS RAM
keep-alive applications.

The EUP7201 is designed to work with ceramic
capacitors on the output to take advantage of the benefits
they offer: for capacitance values in the range of 1µF to

4.7µF range, ceramic capacitors are the smallest, least
expensive and have the lowest ESR values (which makes
them best for eliminating high frequency noise). The
ESR of a typical 1µF ceramic capacitor is in the range of
20mΩ to 40mΩ, which easily meets the ESR requirement
for stability by the EUP7201.

The ceramic capacitor’s capacitance can vary with
temperature. The capacitor type X7R, which operates
over a temperature range of -55°C to +125°C, will only
vary the capacitance to within ±15%. Most large value
ceramic capacitors (

2.2µF) are manufactured with Z5U
or Y5V temperature characteristics. Their capacitance
can drop by more than 50% as the temperature goes from
25°C to 85°C. Therefore,

X7R is recommended over Z5U

and Y5V in applications where the ambient temperature
will change significantly above or below 25°C.

On/Off Input Operation

The EUP7201 is turned off by pulling the

V

EN

pin low,
and turned on by pulling it high. If this feature is not used,
the V
output on at all time.
signal source used to drive the V

pin should be tied to VIN to keep the regulator

EN

To assure proper operation, the

input must be able

EN

to swing above and below the specified turn-on/off
voltage thresholds listed in the Electrical Characteristics
section under V

and VIH.
