LD2213
500mA Ultra Low Dropout Positive Voltage Regulator
General Description
• LD2213 is an ultra low dropout positive voltage regulator with a dropout of 350mV (typical)
at 500mA output current. It provides very low noise, very low standby current (1uA Max) and
excellent power supply ripple rejection (PSRR) 75dB at 100Hz in battery power applications,
such as handsets and PDAs and RF communication applications.
• LD2213 is available in 3 fixed output voltages: 2.5V, 3.0V,3.3V. It could provide output volage
accuracy within ±1.0% at 25°C and ±2.0% over full temperature range.

Note1: Absolute maximum ratings indicate limits beyond which damage to the device may occur.
Recommend operating ratings indicate conditions for which the device is functional, but do not guarantee
specific specification limits. For guarantee specification and test conditions, see the Electrical Characteristics,
the guarantee specification apply only for the test conditions listed. Some performance characteristics may
degrade when the device is not operated under the listed test conditions.
Note2: The Max power dissipation is a function of TJ(max), θJA and TA .The maximum allowable power dissipation
at any temperature is PD(Max)=(TJ(max)-TA)/ θJA, Exceeding the maximum allowable power dissipation will result
in die temperature and the Regulator will go into thermal shutdown

Note3:Specification in Bold typeface are limited to -40°C≤TJ ≤125°C.Limited over temperature are guaranteed by
design, but not tested in production.
Note4: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 500mA.Changes in output voltage due to heating
effects are covered by the thermal regulation specification.
Note5: Output voltage temperature coefficient is defined as the worst case voltage change divided by the total
temperature range.
Note6:Ground Pin current is the regulator quiescent current plus pass transistor base current.The total current
drawn from the supply is the sum of the load current plus the ground pin current.
Note7:Dropout voltage is defined as the input to output differential at which the output voltage drop 1.0%
(TJ=25°C) or 2.0% (-40°C≤TJ ≤125°C) below its nominal value measured at 1V differential.

500mA Ultra Low Dropout Positive Voltage Regulator
LD2213
Typical Application (Note8)
Note8:Dropuout voltage is 350mV when TJ=25°C.In order to obtain a normal output voltage,VO+0.35V is the
minimum input voltage which will result in a low PSRR, imposing a bad influence on system. Therefore, the
recommended input voltage is VO+1V to 18V.For LD2213-2.5 Version, Its input voltage can be set from 3.5V
(VO+0.5V) to 18V.
Application Notes
Input Capacitor
A1uF minimum capacitor is recommended to be place between VIN and GND
Output Capacitor
It is required to prevent oscillation.1uF minimum is recommended when CBYP is unused.2.2uF minimum is
recommended when CBYP is 100uF.The output capacitor may be increased to improve thransistant response.
Nosie Bypass Capacitor
Bypass capacitor is connected to the internal voltage reference.A 100pF capacitor connected from BYP to
GND make this reference quiet,resulting in a significant rduction in output noise,but the ESR stabel area will
narrowed. The start-up speed of the LD2213 is inversely proportional to the value of reference bypass
capacitor. In some cases, if output noise is not a major concern and rapid turn-on is necessary, omit CBYP
and BYP open.
Power Dissipation
Thermal shutdown may occur if exceeding the maximum power dissipation conditions, the junction
temperature must be within the range specified under absolute maximum ratings to avoid thermal shutdown.

Page 14 of 17
500mA Ultra Low Dropout Positive Voltage Regulator
LD2213
To determine if the power dissipated in the regulator reaches the maximum power dissipation (Fig9 and
Fig10), the formula is:TJ=TA+PD*θJA; PD=(VIN-VO)*IO+VIN*IGND. Where: TJ≤TJ (max) is absolute maximum
rating for the junction temperature; VIN*IGND can be ignored due to the small value. TJ (max) is 150°C, θJA is
90°C/W for DPAK (TO-252) package and 160°C/W for SOP-8 package.Example: For 2.5V version packaged
in SOP-8, IO=500mA,TA=30°C,
VIN(max) =(150°C-30°C)/(0.5A*160°C/W)+2.5V=4.0V, therefore ,for good performance, please make sure
that input voltage is less than 4.0V without heat-sink when TA=30°C,
