I am observing a surge startup current of 0.1 to 0.2 mA when I am powering the nRF24LE1 module. Is it possible that the device can startup in power saving mode? Is there a way we can prevent the surge startup current?

While the chip is in reset state (for instance VDD ramp up and settle) and until code execution put the chip in sleep state, then it will likely draw current in the range you state.

Waiting for your reply.
You should have already received links to multiple examples that put the chip to power down mode here:

Can the first lines of my code be like this?
Void main() { PWRDWN = 0x04; PWRDWN = 0x00; mcu_init(); gzll_init(); hal_clk_set_freq(HAL_CLK_125KHZ); //if you put in 125Khz then uart wont work WUOPC0 = 0x02;
Will this do the job?
