Expected current reduction not happen in sleep mode

Hi,

I am Balaji. I am working on LPC 1768 controller. When the controller is in sleep mode, I can't achieve the current reduction specified in the data sheet. I have attached some test results below for your reference. Kindly give me some solution.

Controller	LPC 1768
Voltage(RPS)	3.3 v
Expected current reduction specified in datasheet	2mA

Current reduced when the controller is in sleep mode	Peripherals Enabled
26mA	GPIO,Timer0
25mA	GPIO
23mA	Timer 0
22mA	All Peripherals disabled
