200mA High Speed LDO Regulator, Output Capacitor-Less, Low Power Consumption
■GENERAL DESCRIPTION
The XC6501 series is a high speed, low noise CMOS LDO regulator that can provide stable output voltages even without a load capacitor C externally. The series consists of a reference voltage source, driver transistor, error amplifier, current limit circuit, and phase compensation circuit.
The CE function enables the circuit to be put into stand-by mode by inputting a low level signal to the CE pin thereby reducing current consumption from an already low 13μA (in operation) to less than 0.1μA. In the stand-by mode, if a C the electric charge stored at CL can be discharged via the internal auto-discharge switch and as a result, the V returns to the V
The current limit fold-back circuit operates as a short circuit protection and a current limiter function for the output pin.
■APPLICATIONS
●Mobile phones （RF, NFC, I/O etc.）
●Portable games
●Camera modules
●Wireless LAN modules
●LCD modules
●Bluetooth
●Digital-TV tuners

■OPERATIONAL EXPLANATION
The voltage divided by resistors R1 & R2 is compared with the internal reference voltage by the error amplifier. The P-channel MOSFET which is connected to the V is controlled & stabilized by a system of negative feedback. The current limit circuit and short protect circuit operate in relation to the level of output current. Further, the IC's internal circuitry can be shutdown via the CE pin's signal.
<CL High Speed Auto-Discharge Function>
The XC6501B/D series can discharge the electric charge in the output capacitor C enables a whole IC circuit turn off, is inputted via the N-channel transistor located between the V shown in the BLOCK DIAGRAM. The CL auto-discharge resistance value is set at 400Ω(V The discharge time of the output capacitor C setting time constant of a C
auto-discharge resistance value R
L
the output voltage after discharge via the N-channel transistor is calculated by the following formulas.
<Current Limiter, Short-Circuit Protection> The XC6501 series’ fold-back circuit operates as an output current limiter and a short protection of the output pin. When the load current reaches the current limit level, the fixed current limiter circuit operates and output voltage drops. When the output voltage is shorted to the V

<CE Pin> The IC's internal circuitry can be shutdown via the signal from the CE pin with the XC6501 series. In shutdown mode output at the V

● USPN-4 Power Dissipation
Power dissipation data for the USPN-4 is shown in this page. The value of power dissipation varies with the mount board conditions. Please use this data as one of reference data taken in the described condition.
1. Measurement Condition (Reference data)
Condition: Mount on a board
Ambient: Natural convection
Soldering: Lead (Pb) free
Board: Dimensions 40 x 40 mm (1600 mm2 in one side)
Copper (Cu) traces occupy 50% of the front and
50% of the back.
The copper area is divided into four block,
one block is 12.5% of total.
The USPN-4 package has for terminals.
Each terminal connects one copper block in the front
and one in the back.
Material: Glass Epoxy (FR-4)
Thickness: 1.6 mm
Through-hole: 4 x 0.8 Diameter
