ETR0337-003

Output Capacitor-Less, Low Power Consumption, High Speed LDO Regulator

■GENERAL DESCRIPTION

The XC6501 series is a 6.0V high speed, low noise CMOS LDO regulator that can provide stable output voltages within a range

of 1.2V to 5.0V (0.05V increments) even without a load capacitor C_L. This is possible because phase compensation is carried

out internally unlike other LDOs where it is done 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_Lcap is used, the

electric charge stored at C_Lcan be discharged via the internal auto-discharge switch and as a result, the V_OUTpin quickly returns

to the V_SSlevel.

The current limit fold-back circuit operates as a short circuit protection and a current limiter function for the output pin.

■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_OUTpin is then driven by the subsequent output signal. The output voltage at the V_OUTpin

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.

<C_LHigh Speed Auto-Discharge Function>

The XC6501B/D series can discharge the electric charge in the output capacitor C_L, when a low signal to the CE pin, which

enables a whole IC circuit turn off, is inputted via the N-channel transistor located between the V_OUTpin and the V_SSpin as

shown in the BLOCK DIAGRAM. The C_Lauto-discharge resistance value is set at 400Ω(V_OUT=5.0V @ V_IN=6.0V at typical).

The discharge time of the output capacitor C_Lis set by the C_Lauto-discharge resistance R and the output capacitor C_L. By

setting time constant of a C_Lauto-discharge resistance value Rdischg and an output capacitor value C_Las τ (τ=C x

Rdischg), the output voltage after discharge via the N-channel transistor is calculated by the following formulas.

V = V_OUT(E)x e –t/τ, or t=τx In (V_OUT(E)/ V )

where V : Output voltage after discharge, V_OUT(E): Output voltage, t : Discharge time,

τ: C_Lauto-discharge resistance Rdischg x Output capacitor C_L

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_SS, its current flow reached and minimized to about 25mA.

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_OUTpin will be pulled down to the V_SSlevel via R1 & R2. However, as for the XC6501B/D series, the C_Lauto-discharge

resistor is connected in parallel to R1 and R2 while the power supply is applied to the V_INpin. Therefore, time until the V_OUTpin

reaches the V_SSlevel becomes short. The output voltage becomes unstable, when the CE pin is open. If this IC is used with

the correct output voltage for the CE pin, the logic is fixed and the IC will operate normally. However, supply current may

increase as a result of through current in the IC's internal circuitry when medium voltage is input.

■NOTES ON USE

1. Please use this IC within the stated absolute maximum ratings. The IC is liable to malfunction should the ratings be

exceeded.

2. This IC achieves stable operation without an output capacitor C_Lby internal phase compensation. However, wiring

impedance is high, operations may become unstable due to noise and/or phase lag depending on output current.

Please wire the input capacitor C_INand the output capacitor C_Las close to the IC as possible.
