Ultra High Accuracy,Low Iq, 500 mA
Low Dropout Regulator
The NCP3335A is a high performance, low dropout regulator. Withaccuracy of ±0.9% over line and load and ultra-low quiescent currentand noise it encompasses all of the necessary features required bytoday's consumer electronics. This unique device is guaranteed to bestable without a minimum load current requirement and stable withany type of capacitor as small as 1.0 mF. The NCP3335A also comesequipped with sense and noise reduction pins to increase the overallutility of the device. The NCP3335A offers reverse bias protection.

NCP3335A
APPLICATIONS INFORMATION
Reverse Bias Protection
Reverse bias is a condition caused when the input voltagegoes to zero, but the output voltage is kept high either by alarge output capacitor or another source in the applicationwhich feeds the output pin.
Normally in a bipolar LDO all the current will flow fromthe output pin to input pin through the PN junction withlimited current capability and with the potential to destroythe IC.
Due to an improved architecture, the NCP3335A canwithstand up to 7.0 V on the output pin with virtually nocurrent flowing from output pin to input pin, and onlynegligible amount of current (tens of mA) flowing from theoutput pin to ground for infinite duration.
Input Capacitor
is recommended to further reduce output noise and improvestability.
Adjustable Operation
The output voltage can be set by using a resistor divideras shown in Figure 2 with a range of 1.25 to 10 V. Theappropriate resistor divider can be found by solving theequation below. The recommended current through theresistor divider is from 10 mA to 100 mA. This can beaccomplished by selecting resistors in the kW range. Asresult, the Iadj*R2 becomes negligible in the equation andcan be ignored.
Vout+1.25*1)R1)Iadj*R2
R2ǒǓ(eq. 1)
An input capacitor of at least 1.0 mF, any type, isrecommended to improve the transient response of theregulator and/or if the regulator is located more than a fewinches from the power source. It will also reduce the circuit'ssensitivity to the input line impedance at high frequencies.The capacitor should be mounted with the shortest possibletrack length directly across the regular's input terminals.
Output Capacitor
Example:
For Vout = 2.9 V, can use R1 = 36 kW and R2 = 27 kW.
1.25*1)36ĂkW+2.91ĂV
27ĂkWDropout Voltage
ǒ
Ǔ(eq. 2)
The voltage dropout is measured at 97% of the nominaloutput voltage.
Thermal Considerations
The NCP3335A remains stable with any type of capacitoras long as it fulfills its 1.0 mF requirement. There are noconstraints on the minimum ESR and it will remain stable upto an ESR of 5.0 W. Larger capacitor values will improve thenoise rejection and load transient response.
Noise Reduction Pin
Internal thermal limiting circuitry is provided to protect theintegrated circuit in the event that the maximum junctiontemperature is exceeded. This feature provides protectionfrom a catastrophic device failure due to accidentaloverheating. This protection feature is not intended to be usedas a substitute to heat sinking. The maximum power that canbe dissipated, can be calculated with the equation below:
PD+
TJ(max)*TA
RqJA
(eq. 3)
Output noise can be greatly reduced by connecting a 10 nFcapacitor (Cnr) between the noise reduction pin and ground(see Figure 1). In applications where very low noise is notrequired, the noise reduction pin can be left unconnected.For the adjustable version, in addition to the 10 nF Cnr, a68 pF capacitor connected in parallel with R1 (see Figure 2)
For improved thermal performance, contact the factoryfor the DFN package option. The DFN package includes anexposed metal pad that is specifically designed to reduce thejunction to air thermal resistance, RqJA.
