LD2985Axx
LD2985Bxx
Very low drop and low noise voltage regulator low ESR
capacitors compatible, with inhibit function
Features
■
Very low dropout voltage (280 mV at 150 mA
and 7 mV at 1 mA load)
■
Very low quiescent current (2 mA typ. at 150
mA load and 80 µA at no load)
■
Output current up to 150 mA
■
Logic controlled electronic shutdown
■
Output voltage of 1.8, 2.5, 2.7, 2.8, 3, 3.3, 5 V
■
Internal current and thermal limit
■
Available in ± 1 % tolerance (at 25 °C, A
version)
■
Low output noise voltage 30 mVrms
■
Smallest package SOT23-5L
■
Temperature range: -40°C to 125 °C
SOT23-5L
means that when the device is used as local
regulator, it is possible to put a part of the board in
standby, decreasing the total power consumption.
An external capacitor, CBYP = 10 nF, connected
between bypass pin and GND reduce the noise
to 30 µVrms.
Description
The LD2985A/Bxx is a 150 mA fixed output
voltage regulator. The ultra low drop voltage and
the low quiescent current make them particularly
suitable for low noise, low power applications, and
in battery powered systems. In sleep mode
quiescent current is less than 1 µA when INHIBIT
pin is pulled low. Shutdown logic control function
is available on pin 3 (TTL compatible). This
Table 1.
Typical application are in cellular phone, palmtop
laptop computer, personal digital assistant (PDA),
personal stereo, camcorder and camera.

6.1
External capacitors
LD2985Axx - LD2985Bxx
Like any low-dropout regulator, the LD2985 requires external capacitors for regulator
stability. This capacitor must be selected to meet the requirements of minimum capacitance
and equivalent series resistance. We suggest to solder input and output capacitors as close
as possible to the relative pins.
6.2
Input capacitor
An input capacitor whose value is 1 µF is required with the LD2985 (amount of capacitance
can be increased without limit). This capacitor must be located a distance of not more than
0.5" from the input pin of the device and returned to a clean analog ground. Any good quality
ceramic, tantalum or film capacitors can be used for this capacitor.
6.3
Output capacitor
The LD2985 is designed specifically to work with ceramic output capacitors. It may also be
possible to use Tantalum capacitors, but these are not as attractive for reasons of size and
cost. By the way, the output capacitor must meet both the requirement for minimum amount
of capacitance and ESR (equivalent series resistance) value. Due to the different loop gain,
the stability improves for higher output versions and so the suggested minimum output
capacitor value, if low ESR ceramic type is used, is 1 µF for output voltages equal or major
than 3.8 V, 2.2 µF for VO going from 1.8 to 3.3 V, and 3.3 µF for the other versions. However,
if an output capacitor lower than the suggested one is used, it's possible to make stable the
regulator adding a resistor in series to the capacitor.
6.4
Important
The output capacitor must maintain its ESR in the stable region over the full operating
temperature to assure stability. Also, capacitor tolerance and variation with temperature
must be considered to assure the minimum amount of capacitance is provided at all times.
This capacitor should be located not more than 0.5" from the output pin of the device and
returned to a clean analog ground.
6.5
Inhibit input operation
The inhibit pin can be used to turn OFF the regulator when pulled low, so drastically
reducing the current consumption down to less than 1 µA. When the inhibit feature is not
used, this pin must be tied to VI to keep the regulator output ON at all times. To assure
proper operation, the signal source used to drive the inhibit pin must be able to swing above
and below the specified thresholds listed in the electrical characteristics section under VIH
VIL. Any slew rate can be used to drive the inhibit.

Application notes
Reverse current
The power transistor used in the LD2985 has not an inherent diode connected between the
regulator input and output. If the output is forced above the input, no current will flow from
the output to the input across the series pass transistor. When a VREV voltage is applied on
the output, the reverse current measured flows to the GND across the two feedback
resistors. This current typical value is 160 µA. R1 and R2 resistors are implanted type;
typical values are, respectively, 42.6 kΩ and 51.150 kΩ.
